Be careful using eBay, a rather scary number of listings on there are people just relisting items from Amazon at a higher price and reshipping (or just ordering with your shipping address, I had one eBay purchase come directly from Amazon).

There are plenty of terrible sellers on ebay, too, but it is much easier to sort out the garbage sellers. Seller feedback is right there in the search results, and though you can't filter by feedback any more, it is easy enough to just skip over any listings with a low number or less than 99.9% positive.
