Marshalls Garden Code Checks, Day by Day

Every Marshalls Garden code check from the last 12 days, plotted by the day it ran. Green is how many came back working. Red is how many marshallsgarden.com would not accept. That is the checkout testing you did not have to sit through yourself.

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 marshallsgarden.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 Marshalls Garden 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.

How We Verify Marshalls Garden Codes

Nothing goes up here on trust. A Marshalls Garden code is collected, applied to a real marshallsgarden.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.
