Best Times to Shop

Timing your purchase can lead to big savings. Thompson & Morgan runs excellent seasonal sales. Look for their "Spring Sale" or "Autumn Planting" events where many items are reduced. The end of a season is also a smart time to buy, as they often discount bulbs or seeds to clear stock. Major holidays like Black Friday, Cyber Monday, and Boxing Day are also prime times for site-wide promotions and special offers.

Using Their Rewards Program

Thompson & Morgan has a great free loyalty program called TM Rewards. You earn points, called "TM Credits," on every pound you spend. These credits are automatically added to your account and can be used like cash on your next order.
