Made two purchases and both were cancelled by the app because the sellers didn't send them in time. It seems a bit pointless to cancel the purchase because if I'd been waiting for a week already and wouldn't have minded waiting a few more days for what I ordered. At least I got my money back! Also, a note on the sizing - I think it's pretty poor to refer to a UK 14 as XL when most other stores call this a medium/large. To list a UK 10 as medium and UK 12 as large is bound to cause problems.
