What I mean is,
that sooner rather than later pretty much all retail will be conducted on-line.I have seen it first hand, and whether or not you like it , it's a done deal. Ebay and many other online retailers have put extreme security checks in place to make it as safe as if you are going to a store. And as far as getting ripped off by a seller on eBay, you have to do your research and check into the seller(Feedback) and email people who have purchased items from them in the past, this way you can get a good idea about what kind of seller they are.
I have personally been ripped off more in person(at a store) than on-line.
True, being cautious is a good thing, but also you have to learn to live and grow with new technology and ways of doing things:)
