I've just ordered loads of maternity clothes in different sizes from Mothercare's website because I've no idea what will fit (I'm a different size depending on what shop I go to!) and they don't seem to have much in stock at our branch. I ordered over £150 so got free delivery but won't be keeping all of it (can't actually afford to spend that much on maternity clothes!) - but now I've placed my order I'm worrying about getting my money back for things I don't want. Is it easy enough to take them back to the shop and get refunds for the things I don't want or will they quibble?
