Hahaha, Umm.. Personally, I think you should go to a local liquidation store, usually they have a large variety of them in stock, from refunds from bigger companies, usually, 80% of them work, but they are always in their original packaging, usually you should be able to get them for 12 dollars or so each, and can resell them. This is what I do, but if not, I wont recommend ordering them online, because the suppliers on salehoo, are a little over priced.
