Mack Weldon Code Checks, Day by Day

Every Mack Weldon code check from the last 14 days, plotted by the day it ran. Green is how many came back working. Red is how many mackweldon.com would not accept. That is the checkout testing you did not have to sit through yourself.

where this data came from:
67 automated cart runs14 web search results12 published by the store5 shoppers reporting back

5 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 mackweldon.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 Mack Weldon 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 Mack Weldon

What shoppers ask most about Mack Weldon.

›Can I use multiple promo codes on a single order?

No, Mack Weldon only allows one promo code per order. You cannot stack welcome discounts with community hero codes or ongoing promotional markdowns.

›Do promo codes apply to all items on the site?

Promo codes apply exclusively to full-priced items and never work on final sale products, gift cards, or specific select brand collaborations.

›How often can I reuse my community hero discount code?

Community hero codes obtained via GovX are single-use, but eligible military personnel and teachers can request a fresh code every six months.

›Does Mack Weldon offer a try-on guarantee for first-time buyers?

Yes, the Try On Guarantee allows first-time underwear buyers to get a size replacement or store credit refund if they are unhappy with the fit.

How We Verify Mack Weldon Codes

Nothing goes up here on trust. A Mack Weldon code is collected, applied to a real mackweldon.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 Mack Weldon Shoppers

Not every Mack Weldon code reaches us from the store. 7 codes on this page were first submitted by shoppers. They have also sent back 5 checkout results in the last 14 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 mackweldon.com cart. If it works, it lands here with the test behind it.

Did a code work for you?

Open any Mack Weldon 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.
