Most of what malls around here have are clothes, just a few tiny shops and a supermarket (food, etc.). Considering there's not much choice in elecroics etc. in the first place, and most of the stuff is just clothes, I don't really care about the salespeople, I just wan't the shirt and shoes, pants, etc. to fit. A large t-shirt in C&A fits me perfectly, but in Primark the XL model is too short, and I need an XXL slim size. If i buy nike sneakers, I sometimes need one or even two numbers larger shoe than with other brands (adidas, reebok,...).
Buying online has been a pain and in case of cheaper stuff, a waste of money, since returning a 9eur shirt meant driving to the post office, packing it up, paying postage to return and wait for a couple of weeks to get 9eur back after spending 10eur to ship stuff back.
