Negative Underwear Code Checks, Day by Day
Every Negative Underwear code check from the last 13 days, plotted by the day it ran. Green is how many came back working. Red is how many negativeunderwear.com would not accept. That is the checkout testing you did not have to sit through yourself.

where this data came from:
22 shoppers reporting back3 automated cart runs2 web search results
22 of these results came from shoppers telling us whether a code worked; the rest come from automated checks and the other sources above. Last confirmed working on . Codes that stop clearing get pulled off this page automatically.
What These Numbers Mean
A code check is one result for one code. Most are our agents applying it to a real cart and reading the order total before and after; the rest come from tracked orders and from shoppers reporting back, as broken down above. Worked means the code was accepted and the total went down. Would not apply means negativeunderwear.com refused it on that cart. That is not the same as the code being fake. The usual reasons are:
- It expired or the store switched it off after it was published.
- It was single-use and had already been redeemed.
- It only covers certain categories, brands or individual products.
- The cart did not reach a minimum spend.
- It is limited to new customers, a first order, or an email sign-up.
- It cannot be combined with an active sale or another code.
- It is tied to a different country, currency or membership.
So a code that failed one check can still work on your cart, and the success rate (checks that worked divided by all checks) is best read as how easily Negative Underwear discounts apply in general, not as a verdict on any single code. Hover any bar in the chart to see that day on its own.

Before You Buy at Negative Underwear
What shoppers ask most about Negative Underwear.
›Can I combine multiple promo codes on a single order?
Only one promo code or discount code can be applied per checkout. Promotional discounts cannot be stacked with other active offers or applied retroactively to previous purchases.
›Do promo codes apply to all items sitewide?
Promo codes apply exclusively to full-priced merchandise and never work on final sale items, gift cards, or specific limited-edition capsule collections.
›Does Negative offer price adjustments if an item goes on sale?
Price adjustments are honored only if an item purchased at full price is marked down within 48 hours of the original order date, issued as store credit.
›Can I include a gift message with my order?
Gift messages can be added directly during checkout on the cart page. Physical gift receipts are included automatically with prices hidden from the packing slip.
How We Verify Negative Underwear Codes
Nothing goes up here on trust. A Negative Underwear code is collected, applied to a real negativeunderwear.com cart, dated the last time it took money off an order, scored on what came back, and pulled once it stops clearing. Promotions have no code to run through a checkout, so those are dated when they go live and dropped when they lapse. Here is how far that has got on this page, and every change the agents logged along the way.

Help Other Negative Underwear Shoppers
Not every Negative Underwear code reaches us from the store. 5 codes on this page were first submitted by shoppers. They have also sent back 22 checkout results in the last 13 days, telling us which codes worked on a real cart and which came up empty. Wherever a code comes from, it still has to pass the same cart test before it goes up here.

Have a code we missed?
Send it over and the agents will run it through a real negativeunderwear.com cart. If it works, it lands here with the test behind it.
Did a code work for you?
Open any Negative Underwear code above and tell us whether it worked. It takes one tap, no sign-up, and a code that keeps failing gets pulled off the page.
