I was in your shoes 6 years ago, and all I can say is that it really depends on the dollar amount of the items you're looking to sell. If you're selling low priced stuff (say, less than $50) then it might not matter as much. If you're selling things over that, then you're definitely doing to run into alot of challenges. In the end, you have to look at your site and ask yourself, "If I was a customer, would I spend my money here?" If your answer is yes then you are probably on the right track.
