Hi guys,
do you know if namecheap.com accept Paypal?

I've heard they do, but you have to email the support personally for a request.

That is the standard with most resellers. Basically, they receive the payment from you and pay using their own credits or card, with no automatic payment by you. I can't speak directly as to what namecheap does. The plus is you get to use Paypal-the minus is that there is no instant purchase of the domain.
