Checking online sellers, merchants or whatever you want to call them.

I buy a lot of stuff online these days. In fact, outside of groceries, cars and major appliances, I can say rather honestly that I buy everything else online. From auto parts to clothing to DVDs and books, they're all online to be had and you can comparison shop on prices. The web is just an amazing resource!

The only problem is whether or not you can trust these e-merchants that you find a great bargain on. The old adage, "If it's too good to be true, it probably is," applies here. While you can find good bargains, you risk getting ripped off. So the question is, how can you be fairly certain it is really a good bargain?
