The Entertainer have the £8 off £30 spend, which includes all Fingerlings. So you can get the 2 tone for £10 if you buy 2 and Unicorn and Glitter ones would be £13 each. Considering these are never any cheaper (unless fake) I thought this worked out a bargain! No weird catch, just log in with your Amazon details and it gives you the code. Can pay as normal however you choose.
