Paypal and Ebay

Do you have a Paypal account?
Do you like it?
Have you had any problems with it?
Also with Paypal can you use a debit card instead of a credit card?

Do you shop on eBay?
Have you had a lot of luck with it?
Have you ever been ripped off?


Sometimes I think I'd like to use these things. But. I just. I just don't know if I trust things.
