I don't know but that's totally understandable to me. Sucks that it happened but they do keep tabs on customers that seem to be buying too much. Even if 20% of what you bought was to sell on ebay then they have the right not to sell to you if you don't go by their rules so to speak. I used to work at Tiffany's and they would do the same thing, they were always on the lookout for people buying too much and selling on ebay.
