I use paypal for paying for stuff or sending or accepting money. It's the easiest way to pay for eBay purchases. I like it and will continue to use it.
Only one thing that bother me, that is PayPal has own currency exchange courses and they are not so good as in your bank. So it's more useful to change your Paypal settings if you purchase something form Europe or other countries.
For example if u use USD card and are going to purchase in another currency. Either PayPal or your bank can do it. So, you need to change your settings to save money, cause your bank currency exchange is better the PayPal's course.
Just go to your settings, - click "conversion options" and choose "Bill me in the currency listed in the seller's invoice".
