I have difficulty with busy crowded stores as well, so I love having the option of buying online. Plus, our prices are so expensive for a lot of goods here in Au., that it's often cheaper to buy online and have them delivered from overseas. (I'm sure our present govt. will put an end to that as soon as they can! )

I don't buy too much but have bought things from ebay and used paypal and never had a problem.

I have bought from new sellers. I have no problem buying from regular people rather than the ebay stores. One has to start somewhere, so many have just started using the site and are trying to make a bit of cash. I have found them all on the ball with fast delivery and fast messages etc.. The reputation system with ebay is a good idea and helps regulate standards to a certain extent. I always read reviews if I'm going to buy something.
