What does TPD mean on a Costco receipt?

TPD is widely reported by shoppers to stand for temporary price discount: a markdown funded by Costco itself and applied automatically at the register. It prints as a separate negative line, usually TPD followed by a slash and the item number of the discounted product. Costco does not publish an official legend for receipt codes, so this is shopper-reported convention.

What is IRC on a Costco receipt?

IRC is commonly reported to stand for instant rebate coupon: a manufacturer-funded instant rebate, often from the monthly member savings booklet. Like a TPD it prints as its own negative line tied to the discounted item and applies automatically at checkout, with no coupon to present.

Does TPD mean I already got the discount?

Yes. A TPD line with a negative amount means the markdown was already deducted from your total at the register. If a TPD markdown starts after you bought the item at full price, that is a price drop you can raise under Costco's 30-day price adjustment policy instead.

Costco receipt codes explained: TPD, IRC, and more

Costco receipts are dense with abbreviations, and a few of them show up as their own line items with negative amounts attached. The two you will see most often are TPD and IRC, and knowing the difference tells you which kind of discount you received and whether there is still money on the table. Costco does not publish an official legend for these codes, so the meanings below are the conventions consistently reported by shoppers, with the hedges that deserves. This guide covers each code one at a time, then explains what they mean when you are thinking about a price adjustment.

TPD: temporary price discount

TPD is widely reported by shoppers to stand for temporary price discount (some say temporary price decrease, same idea). It appears on the receipt as its own line with a negative amount, usually printed as TPD followed by a slash and the item number of the product being discounted, for example TPD/1234567. That format is the clue: the TPD line is not a product you bought, it is a markdown applied to a product elsewhere on the receipt.

A TPD is Costco's own markdown, applied automatically at the register. There is nothing to clip or present, and the cashier does not have to do anything. If the item is on a temporary discount, the register deducts it. The practical takeaway: if you see a TPD line tied to an item, the discount was already applied to that purchase, and the negative amount tells you exactly how much you saved.

Format: a separate negative line, commonly TPD/ followed by the item number it discounts.
Commonly reported meaning: a temporary markdown funded by Costco itself.
Applied automatically at the register; no coupon or action needed.
A TPD line means that discount is already reflected in your total.

IRC: instant rebate coupon

IRC is commonly reported to stand for instant rebate coupon, and it is how many of the instant savings from Costco's monthly member savings booklet show up at the register. Like a TPD, it prints as a separate negative line tied to an item, so the shelf price appears at full value and the IRC line subtracts the savings before the total.

The commonly reported distinction is the funding source: an IRC is a manufacturer-funded instant rebate, while a TPD is Costco's own markdown. From your side of the register the effect is identical, an automatic deduction with no coupon to present. Costco's instant savings apply automatically at checkout, which is why the company says you do not need to clip anything.

Format: a separate negative line tied to the discounted item, like a TPD.
Commonly reported meaning: a manufacturer-funded instant rebate, often from the monthly savings booklet.
Applies automatically; Costco does not accept physical manufacturer coupons.

IRC vs TPD: what is the difference?

Both codes are discounts, both print as negative lines tied to an item number, and both are applied automatically. The difference shoppers consistently report is who funds the discount: TPD is Costco marking down its own price temporarily, while IRC is a manufacturer rebate passed through instantly at the register.

Why care? Mostly for reading your receipt accurately. If you expected a booklet deal and see neither line, compare the price you paid against the advertised price, because a missing deduction is worth raising with Costco. And if you are tracking whether an item's price dropped after you bought it, a TPD that starts after your purchase date is exactly the kind of drop Costco's 30-day price adjustment exists for.

TPD: Costco's own temporary markdown, commonly reported.
IRC: manufacturer-funded instant rebate, commonly reported.
Identical at checkout: both deduct automatically as their own receipt line.
Neither one appearing when you expected a deal is a reason to check with Costco.

GP and other fee or deposit lines

GP is one of the murkier codes. Shopper reports most often tie it to fee or deposit lines, for example bottle or container deposits in regions that charge them, where the deposit prints as its own small line near the item. Unlike TPD and IRC these lines are usually positive amounts, a charge rather than a discount.

Reports on GP vary more by region than the other codes, so treat this one as especially unofficial. If a small unexplained line matters to you, the reliable move is to ask at the membership counter, since the meaning can depend on your state or province's deposit and fee rules rather than anything Costco decides.

Commonly reported as a fee or deposit line, such as bottle deposits, depending on region.
Usually a small positive charge, not a discount.

The mark the door checker makes

On your way out, the employee at the exit compares your receipt against your cart and marks it, often with a swipe of highlighter or a scribble that shoppers sometimes report doubles as a quick tally code. Costco does not publish what the checkers verify or what the marks mean, and reports vary by warehouse, so this is folklore territory. The practical point is simply that a marked receipt shows it was checked on the way out.

Tax letters like A and E

The single letters printed next to items or prices are generally tax-status indicators. A is commonly reported to mark a taxable item and E a tax-exempt one, often qualifying food, but the letters follow your state and local tax rules rather than a single Costco-wide legend. Our receipt guide covers these in full, including the FSA and HSA related letters some shoppers report.

A: commonly reported as taxable; E: commonly reported as tax-exempt.
The letters track state and local tax rules, not one official Costco legend.

What these codes mean for a price adjustment

Here is where the codes become more than trivia. Costco offers a price adjustment on its own price drops within 30 days of purchase: if something you bought gets cheaper, you can request the difference back. A TPD markdown that begins after your purchase date is precisely that scenario. You paid full price, the item now rings up with a TPD deduction, and the difference is claimable inside the window.

Your receipt has everything you need to check: the item number on each line and the purchase date at the top. Policies can change, so confirm the current terms on Costco's official customer service pages before you count on a refund.

A TPD that starts after you bought is a claimable price drop inside the 30-day window.
The item number and purchase date on your receipt are what you need to check a drop.
The window is 30 days from the purchase date, per Costco's stated policy.
