I bought 12pairs of GUCCI, LV shoes from this company http://www.in-brands.com last week. Tell honestly, the quality of shoes is really good and the price is reasonable, but the size of 6 pairs are wrong, smaller than what I want, how do I sell them? My customers need big size shoes, I want to change the shoes, but the company said that I had to pay shipping charge first, it is not my fault, why do I have to pay the shipping charge?
