To add to this discussion, it's worth mentioning that if you make online purchases using Paypal, at least you have a chance to get your money back. It is, of course preferable to prevent being scammed as Iron Patch mentioned, however, if you have the misfortune of buying into a scam, take it up with Paypal (if you use them) and they'll most likely refund your money based upon, among other things, the seller's history and your physical proof that you were scammed. I recently had the misfortune of buying a pair of shoes online and received a typical household sponge instead (return address was in China). It turns out the website I purchased from was a fake, hosted by a Chinese scammer. I was able to get my money back through Paypal, but I would have preferred to avoid the whole business altogether. The agents at Paypal (and eBay for that matter) are well aware of the scams/scammers, who quickly create a new website to fool people once the current website loses its reputation. I thought it was funny to hear the agent say, "at least you got a sponge, most people get a hairnet." Good luck out there, and be cautious!
