paypal is a bad idea, if paypal does not like what you are selling, then this can get your paypal account limited, and i do not want to risk my paypal account which is used to pay for other services..... I recently applied via stripe, and stripe responded by saying... We do not accept drop-shipping.... how are you guys accepting payments?
We are accepting paypal and so far we didn't have any serious problems with security or successful orders. Aside from that, we also accept major credit cards and bank transfer methods.
We accept PayPal and use 2CheckOut also, as well as Authorize.net. We have been happy with all three. If you want a good reseller for Authorize.net, contact me offline and I can send you one. We are very happy with the person we used.
