Thompson & Morgan Code Checks, Day by Day

Every Thompson & Morgan code check from the last 14 days, plotted by the day it ran. Green is how many came back working. Red is how many thompson-morgan.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 thompson-morgan.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 Thompson & Morgan 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 Thompson & Morgan

What shoppers ask most about Thompson & Morgan.

›Can multiple promotional discount codes be applied to a single order?

Only one promotional code or voucher key can be used per transaction at checkout. Promotional vouchers are personal to each individual and cannot be stacked with other offers or applied retrospectively.

›Are there any items or product categories excluded from promotional codes?

Promotional codes never apply to third-party Marketplace vendor items, eGift vouchers, or select pre-cleared promotional lines unless explicitly stated otherwise in the offer terms.

›Why do different plant varieties arrive on different days?

Each plant variety or product is packed separately and dispatched at the optimum time for planting according to seasonal growth cycles. You will not incur any extra delivery charges for items shipped across multiple parcels.

›How does the Double Money Back Guarantee operate on select varieties?

For designated 'Grow the Best' varieties, customers who feel they have grown superior specimens can claim a double refund by submitting written details including soil type, location, and fertilizer use by September 30th.

How We Verify Thompson & Morgan Codes

Nothing goes up here on trust. A Thompson & Morgan code is collected, applied to a real thompson-morgan.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.
