KingSize Code Checks, Day by Day

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

where this data came from:
212 automated cart runs27 published by the store20 shoppers reporting back15 web search results

20 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 kingsize.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 KingSize 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.

When KingSize Runs Sales

Recurring events worth timing an order around. Windows shift year to year, so treat them as a shopping calendar rather than a fixed date.

  1. late November
    Black Friday Sitewide Event

    Features sitewide markdowns of 50% or more on seasonal essentials and big and tall winter outerwear.

  2. late January to February
    End of Season Clearance

    Provides extra price drops taking up to an additional 50% off previous-season clearance inventory.

  3. late November
    Cyber Monday Super Sale

    Offers enhanced percentage-off coupon codes alongside free shipping promotions across select departments.

Before You Buy at KingSize

What shoppers ask most about KingSize.

›Can I use more than one promo code on my order?

No, you may only apply a single promo code per order, though it can be combined with automatic site promotions. Exclusions apply to clearance items and select partner brands.

›Which brands or categories are excluded from discount codes?

Promo codes never apply to third-party merchandise, final sale clearance inventory, or select licensed sports league gear from the NFL and NBA.

›Why is my valid-looking promotional coupon code being rejected?

Codes fail if your cart has not met the minimum merchandise subtotal before taxes or if it contains excluded brands like Boulder Creek and Liberty Blues.

›Can gift cards be used on international web purchases?

No, gift cards and e-gift cards purchased in the United States cannot be redeemed for international orders processed through i-parcel.

How We Verify KingSize Codes

Nothing goes up here on trust. A KingSize code is collected, applied to a real kingsize.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 KingSize Shoppers

Not every KingSize code reaches us from the store. 2 codes on this page were first submitted by shoppers. They have also sent back 20 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 kingsize.com cart. If it works, it lands here with the test behind it.

Did a code work for you?

Open any KingSize 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.
