I lost trust in Paypal after one of the most credible, respectable organizations I knew was on the verge of going out-of-business. A lot of people made donations, myself included. Paypal froze and wouldn't release those donations.

I would absolutely never, ever, ever run a business which relied on Paypal.

As a shopper, it works okay, though. I got scammed once, and Paypal did nothing, but the risk isn't very high. It was probably twenty bucks or something, but if it were more, I could raise it with my credit card company.
