Before you pay, slow down at four points: who is selling the item, what you'll actually be charged, what protection the payment method gives you, and what happens if delivery or a return goes sideways. HTTPS can encrypt information sent during checkout, but a padlock doesn't prove a store is legitimate or that it will deliver.

For U.S. purchases, the Federal Trade Commission's online shopping guidance recommends comparing the total cost, reviewing shipping and refund policies, and keeping records. Use the checkpoints below as a gate, not a formality.

Checkout gate

• Start from the retailer's official website or app, not an unsolicited email or text link.
• Check the seller's name, location, contact information, ratings, and return terms.
• Compare the complete price, including shipping, taxes, handling, and other fees.
• Confirm the exact model, size, quantity, condition, warranty, and promised delivery date.
• Make sure checkout uses HTTPS, but don't treat the padlock as proof that the seller is trustworthy.
• Choose a payment method with protections you understand.
• Save the listing, receipt, order number, delivery promise, and return policy.
• Use the seller's official order page to track shipping and resolve problems.

The listing and the final price

A low headline number can hide a different product or a higher checkout total. Write down the exact item details before comparing stores. Model number, size, color, quantity, condition, included accessories, and warranty can separate two listings that look identical in a search result.

Then add every charge that appears at checkout:

• Item price
• Shipping and handling
• Delivery fees
• Sales tax
• Service, marketplace, or processing fees
• Currency-conversion charges from an overseas seller
• Required membership or subscription charges

Deal terms matter too. A discount may require a minimum purchase, enrollment in a recurring program, or acceptance of a final-sale policy. A coupon may apply only to certain sellers or sizes.

Reviews can help, but a star rating isn't proof. Read recent comments for details about the exact product, and compare more than one source. A large review count doesn't make every seller reliable.

Verify the site and the seller

A polished design can be copied. Check the full web address for misspellings, extra words, or a domain that differs from the retailer you meant to visit. If you arrived through a message, close the page and type the retailer's address yourself or use a saved bookmark.

Before entering payment information, look for:

• A business name and a usable way to contact the seller
• Clear shipping, return, refund, and privacy policies
• A description that identifies the seller on a marketplace
• Consistent prices and product details
• A checkout page using https://

HTTPS encrypts information while it travels between your device and the website. It doesn't confirm that the business is honest, that products are genuine, or that you'll receive the order.

Walk away if the seller uses extreme urgency, offers a price far below comparable listings without a clear reason, lacks an address or meaningful customer-service process, uses copied photos or vague descriptions, insists on wire transfer, gift card, or cryptocurrency, or tries to move messages and payment outside a marketplace. No single warning proves fraud, but several together are a good reason to leave.

Shipping deadlines in the U.S.

A seller must follow the shipping time it advertised. If it gives no shipping time, the FTC says the order generally must ship within 30 days after the seller receives your name, address, and payment, or your permission to charge the account.

If the seller can't meet the promised time, the FTC's Mail, Internet, or Telephone Order Merchandise Rule guidance explains that the seller generally must give you a choice: agree to a delay or cancel for a prompt refund. The rule can have exceptions, so review the official guidance for unusual orders.

If an order is late:

1. Check the order page directly, not a link in an unexpected delivery message.
2. Contact the seller through an official channel and ask for a specific shipping date or cancellation.
3. Keep the response and note the date of each contact.
4. If you agreed to a delay and the new date is missed, request cancellation and a refund.
5. Use a marketplace claim or payment-dispute route before its deadline if the seller doesn't resolve the issue.

The shipping rule isn't a general return right. It addresses delivery timing. If you simply change your mind, the seller's written return policy usually controls the available options, subject to any separate law or product-specific protection.

Payment method matters

The payment rail changes your options. A credit-card billing dispute, debit-card claim, digital-wallet dispute, Buy Now, Pay Later complaint, and wire-transfer recovery request don't necessarily follow the same rules.

A digital wallet may limit how many merchants see your card number, but it doesn't remove the need to check the seller. If your card issuer offers virtual card numbers, read how they handle refunds, recurring charges, and canceled orders.

Use a private device and a trusted network for checkout. Avoid entering payment information on a shared computer or public Wi-Fi. Use a unique password for the shopping account and turn on multifactor authentication if the retailer offers it.

Save evidence before and after checkout

Keep enough information to show what you ordered and what the seller promised. Save or screenshot:

• Product page and seller name
• Advertised price and deal terms
• Promised shipping or delivery date
• Return and refund policy
• Final checkout total
• Order confirmation and order number
• Tracking information and messages with the seller

If the package arrives damaged or the item doesn't match the listing, take photos. For an expensive purchase, photograph the package before opening it and the product immediately afterward. Store records somewhere you can access if the marketplace account or listing changes.

Check your card or bank statement after the order. Confirm the amount is correct and watch for an unexpected recurring charge or a second transaction.

Read the return policy before paying

Find the return terms before you place the order, not after the package arrives. Look for:

• Number of days allowed for a return
• Whether the period starts at purchase, shipment, or delivery
• Who pays return shipping
• Restocking or handling charges
• Final-sale and clearance exclusions
• Required packaging, tags, or product condition
• Whether the refund goes to the original payment method
• Whether the seller offers an exchange or store credit instead
• Separate rules for defective, damaged, or incorrectly described items

Marketplace purchases can involve two sets of rules: the individual seller's policy and the platform's buyer-protection policy. Read both. A platform guarantee isn't automatically the same as a refund from your card issuer.

For example, eBay publishes a Money Back Guarantee policy. Eligibility, evidence requirements, and time limits depend on the transaction, so open the current policy and the order-specific instructions before assuming a claim will qualify.

Marketplace, used, and overseas purchases

Marketplace listings

Identify whether the platform itself or an independent seller is responsible for the order. Keep communications and payment on the platform when possible. Moving off-platform can make it harder to show what was promised or use the platform's process.

Check the seller's feedback history, account age, location, handling time, and return terms. For high-value products, confirm serial numbers, authenticity requirements, and insurance or signature delivery.

Used products

Ask for current photos and a precise description of wear, missing parts, repairs, and defects. Verify that the item is compatible with your equipment and that the seller hasn't copied photos from another listing. Don't assume a second-hand item is returnable if the listing says it's sold as-is.

Overseas sellers

Before ordering from outside the U.S., confirm the seller's location, delivery method, currency, taxes, customs duties, and return destination. Return shipping can cost more than the product, and a U.S. shipping rule may not be the practical route for resolving a dispute with an overseas merchant.

What to do if a purchase goes wrong

Use this order of operations:

1. Secure your accounts. If you entered a password on a suspicious site, change it anywhere you reused it. If you entered card information, contact the issuer using the number on the card or statement, not a number in the suspicious message.
2. Contact the seller in writing. State the order number, problem, and remedy you want. Request a response by a reasonable date.
3. Open a marketplace case. Follow the platform's instructions and submit the listing, messages, tracking, photos, and receipt. Watch the filing deadline.
4. Contact the payment provider. Ask which dispute process applies to your payment method. Don't assume a merchant return request, wallet claim, and credit-card billing dispute have the same deadline.
5. Keep copies. Save your complaint, supporting evidence, shipping receipt, tracking number, and every response.

For a U.S. credit-card billing error, the FTC says you generally need to send a written dispute to the card issuer's billing-inquiry address within 60 days after the first statement containing the error was sent. Include your name, account information, disputed amount, and an explanation. Keep a copy and proof of delivery. The FTC's credit-card dispute guidance explains the process, including the issuer's acknowledgement and investigation time limits. The issuer must acknowledge the complaint within 30 days unless the problem is resolved, and it must resolve the dispute within 90 days.

That procedure is for qualifying billing errors, such as an incorrect charge or merchandise that wasn't delivered as agreed. It isn't an automatic remedy for changing your mind. Contact the seller promptly, but don't wait so long that you miss the issuer's deadline.

Fast answers

Does the padlock mean a website is legitimate?

No. HTTPS helps encrypt information sent to the site, but it doesn't verify the business or guarantee delivery. Check the domain, seller identity, contact details, policies, and payment options separately.

How long does a U.S. seller have to ship an online order?

The seller must follow its advertised shipping time. If it made no shipping promise, the order generally must ship within 30 days after the seller receives the information needed to process it. If the seller expects a delay, it generally must offer a choice between accepting the delay and canceling for a prompt refund.

What records should I keep?

Save the listing, final price, seller information, promised delivery date, return policy, confirmation email, tracking, payment record, and seller communications. Take photos if the package or product arrives damaged or differs from the listing.

Should I use a credit card for every online purchase?

A credit card can provide a defined billing-error dispute process, but it isn't a guarantee that every return or complaint will succeed. Compare the protections and deadlines for the specific payment method, and contact the issuer quickly if a charge is fraudulent or the order isn't delivered as agreed.

If you're at checkout now, open the return policy and screenshot the listing before paying. If an order has already gone wrong, start with the deadline that applies to your payment method and keep every response in one place.
