Yes, it's my fault for not checking but it said "Free Replacement & Returns Information" on the item page so silly me for not checking returns costs.
Trousers were £39, they are nice but far too wide legged for me. Shipping was £4 (as under £50 order) and now they are charging £5 to return them. I can send them back with another carrier at my own cost, or free return for store credit +£10 but as there is no way of knowing what fits without paying £5 each time I'm wary of buying anything else, and it's all so expensive.
I thought I might look at one of their coats but I've got the hump now and it's all too much mental weighing up of whether the likelihood of it fitting/suiting is worth the £5 return gamble!
