A restocking fee is the slice of your refund a U.S. retailer keeps after you send an item back under its return rules. Store policy usually sets it.

Thing is, federal law does not publish a nationwide 15% or 20% cap.

Can a copied complaint letter erase that fee? Only if your receipt and screenshots actually undercut the charge. The letter is still worth sending.

It puts the order number, the dollar amount, and a plain request in one dated document. Copy the template below, then delete any line that is not true for your return. Stay polite.

The FTC's sample customer complaint letter uses that same calm structure: who you are, what went wrong, and what you want done.

Re: Restocking fee on order [order number]

Dear Customer Service,

I am writing to dispute a restocking fee of $[amount] withheld from my refund for [item description], purchased on [purchase date] (order [order number], account [account number if any]).

I returned the item on [return date] in [unopened / opened but unused / defective] condition, inside the stated return window of [X days]. I request that you reverse the $[amount] restocking fee and credit the original payment method.

The fee does not match what I was shown, or it does not match this return. Use only the sentence that applies, and delete the others:

The restocking fee was not disclosed on the product page or at checkout before I paid.
Your return policy limits restocking fees to [quote the policy], which does not apply to this return.
The item was defective or not as described ([short facts]).
I returned the goods unopened, in original packaging.

I enclose copies of the receipt, return confirmation, photographs, the refund statement showing the fee, and any policy screenshot I captured.

Please confirm the reversal by email at [your email] within 14 days. If this stays unresolved, I will keep a record through the FTC complaint process and contact my payment provider about the charge.

Sincerely,
[Your name]

A kitchen-sink letter looks sloppy. One true reason beats four guesses.

Fill the blanks, then send it

Write the exact fee in dollars. Rounding to "about 20%" just delays the reply.

To be honest, most stalled disputes are missing an order number or a copy of the refund line.

Here's a simple send order:

1. Replace every bracket with a real name, date, or amount.
2. Attach copies of proof, never your only original receipt.
3. Email the letter and save the sent copy. For a large fee, add a paper copy if you have a mailing address.
4. Write down the date you sent it, then follow up once after about 10 days.

FTC guidance on returns, refunds, and other resolutions tells you to say what you want, keep notes, and save a chat or screenshot before you close the window.

What actually decides the fee

People treat restocking percentages like a national speed limit. They aren't.

The merchant's return policy is the first document that matters. If the fee sat on the product page, again at checkout, and you had to acknowledge it, the retailer will point to that trail.

A fee that popped up only after payment is a different argument.

There is no single federal rule that forces a store to hand you inspection photos before it keeps a restocking charge. That photo demand is a myth. "I think 15% is too high" is weaker than "you never showed me the fee" or "the blender arrived cracked."

Skip canned citations you have not read. Mail-order shipping-time rules do not set restocking percentages.

California Civil Code section 1723 is about conspicuous posting of refund, exchange, and credit policies. It is not a 20% restocking cap. A policy printed only on the receipt can fail that posting standard, because you see it after you pay.

If you bought the item in another state, read that statute before you name it. Wrong code numbers make a letter easy to ignore.

If the goods did not match the listing, say that in plain words. An unopened box is easier to explain than a torn package with missing cables.

Documents that make the letter land

Don't dump a novel. Send copies that show what you bought, what you were told, what you returned, and what they kept.

If the product page changed, say so. Screenshot what is there now anyway.

You start pulling files and then you remember the fee only showed up on the refund email, so you scroll back through order confirmations and payment apps looking for any mention of restocking, and if nothing is there you still send the packet because the missing disclosure is the point, not a perfectly highlighted PDF from checkout.

If the store does not reverse the fee

Turns out the next step depends on how you paid.

Credit cards sit under federal billing-error procedures. Under the CFPB billing error resolution rule (Regulation Z section 1026.13), written notice generally must reach the issuer's billing-inquiries address within 60 days after the statement that first showed the error. Include your name, account number, the dollar amount, and why you think it is wrong.

That process covers listed billing errors, such as a charge you did not authorize, a charge that is not identified as required, or goods not accepted or not delivered as agreed. A restocking fee that matches a disclosed, completed return may not fit. Read the billing-rights notice that came with your account before you assume the issuer will pull the fee.

Debit, prepaid, and store-credit refunds use different rails. Ask that provider which form it wants.

You can report the company to the FTC and your state attorney general. An FTC filing creates a record. It does not order the retailer to pay you. Small claims court is a later option for a leftover amount; dollar limits vary by state.

Print the letter this week, attach the copies, and send it while the return is still easy to pull up. Then set a reminder to look for a written answer.
