I was after a pair of flatform trainers for a wedding. Bought 5 pairs to try. Although they arrived quite quickly, they were all too narrow - some more than others - there's a lack of consistency in sizing. To save return postage costs, I took them back to a store. The harassed assistant in the store plainly found the returns process irritating and was quick to tell me how long it would take for my refund... And she wasn't wrong! I've also tried trainers from M&S and Russell and Bromley - both of whom were much quicker to refund. Don't ask me if you don't want to know!
