uncomfortability buying online

I would say most products are easily verified to be what you are trying to get especially when the seller is a company based manufacturer. I would not be comfortable however with buying most electronics online. The first rule when buying expensive machinery that has to work to be functional is to test it out. I can not feel comfortable until I test it, unfortunately that cannot be done online. Even then certain sites can be trusted with electronics. For instance anything being sold essentially from a store but instead being shipped to your house would have to be as safe as going to pick up the box yourself. Some electronics are packaged so they can not be tested so as long as the store or site has a return policy it is fine by me.
