Is paypal secure enough so that you won't get any scams?
I think it's fairly safe. It's a big business, so it's not like it's some underground operation. It might get hacked, but that's like any site or place.
I use PayPal when I make purchases online, and I haven't had any problems with them at all. In fact, I look for businesses that allow me to use PayPal to pay for something I buy. It's safer than trusting your information to some random website.
