I did that for a while when PayPal first started up, but there was a limit on how long you could continue to do the credit card thing without 'certifying' (or somesuch similar concept) your PayPal account by providing them with bank info.
I used PayPal up to that limit and then stopped.

Perhaps they've changed their ways. I'll have to go see.

edit:
Ok- they've changed the limits. Before it was only a few hundred dollars that you could send before they required 'verification'. Now it is $10k. The Personal (unverified) Account also has receiving and withdrawal limits of $500/mo.
Hmm...
I'm still happy with the charger I selected, but now I have lost my reason *not* to shop at DealExertion.com.
