Last time this happened, I bought the items anyway expecting them to just refund the difference. They couldn't and I ended up returning them for a different reason.
Pretty shitty... hopefully TBS at least gives me a new code to use.
ahah, no, it's actually ASOS, a brand which I wouldn't normally consider because what I've got from them in the past has been really bad quality, but this jacket is at a ridiculous price right now (£20) and it looks pretty good, so I might go for it. Way too much blue in my wardrobe already though
