Thompson & Morgan Promo Codes & Coupons September 2025

If your Thompson & Morgan promo code isn’t working, it’s usually due to an expired code, minimum spend not met, product exclusions, or a typo in the code entry. The site may display error messages like “This code is not valid for your order” or “Promo code expired.”

Common scenarios include:

• Using a code that’s only valid on specific categories (like plants or seeds) but applying it to excluded items such as sale or clearance products.
• Entering a code that has a minimum order value (e.g., “£10 off Orders Over £20”) but your basket doesn’t meet the threshold.
• Trying to use a code that’s already expired or limited to single use per customer.
• Copying the code incorrectly—promo codes are case-sensitive and must be entered exactly as shown.

Step-by-step solution:

1. Double-check the code for typos and correct case.
2. Review the terms and conditions for restrictions (product, category, minimum spend, expiry).
3. Remove any excluded items from your cart and try again.
4. If you’re still having trouble, try a different, recently verified code from a reputable source.

Pro tip: Always check the code’s expiry date and terms before applying, and use a reputable coupon site with live success tracking for the best chance of finding a working code.

Yes, Thompson & Morgan frequently offers promo codes targeted at specific plants, seeds, or gardening categories. These codes often appear as “10% off Garden Ready Plants” or “15% off Pre-planted Baskets,” and sometimes for particular plant varieties like “Sweet Pea ‘Scentsational’ Mix.”

Patterns to watch for:

• Category-specific discounts (e.g., bulbs, seeds, baskets) are common, especially during seasonal promotions.
• Some codes are only valid on selected lines or new arrivals, not on sale or clearance items.
• The code description will usually specify the eligible category or product.

Step-by-step solution:

1. Check the promo code details for category or product restrictions.
2. Add only eligible items to your basket.
3. Enter the code at checkout and confirm the discount applies before completing your order.

Pro tip: For the best deals, sign up for Thompson & Morgan’s newsletter or check their offers page regularly—category-specific codes are often released around planting seasons.

If your promo code has expired, don’t worry—Thompson & Morgan consistently has new and active offers available. There are often codes for sitewide discounts (like 10% or 15% off), as well as special deals on specific categories and free gift card promotions.

What to do:

• Visit reputable coupon sites or Thompson & Morgan’s own offers page for the latest codes—many are updated daily and verified by other shoppers.
• Look for ongoing promotions such as “£10 off Orders Over £20,” “Free £5 Gift Card with Orders Over £25,” or “20% off Selected Orders.”
• Some codes are exclusive to first-time customers or newsletter subscribers.

Step-by-step solution:

1. Search for current, verified codes on trusted coupon platforms.
2. Check the terms for eligibility and expiry.
3. Apply the new code at checkout.

No, Thompson & Morgan only allows one promo code per order. If you try to enter a second code, the checkout system will typically replace the previous code or display a message like “Only one promotional code can be used per transaction.”

Key details:

• Stacking codes is not permitted—choose the code that gives you the best overall discount or value for your order.
• Some offers (like free gifts or free delivery) may apply automatically without a code, but only one manual promo code can be entered.

Step-by-step solution:

1. Compare available codes for the highest savings or best fit for your order.
2. Enter your chosen code at checkout.
3. If you want to switch codes, remove the current one and enter the new code.
