I would go with PayPal Payments Pro. I read a little bit about it ,it sounds suitable to me.
I talked to my client and he agrees with PayPal option but he wants to know if it's secure enough and
ask me these questions that I do not know the answer.
For example if a buyer makes a purchase through this website and seller (my client)receives the money
through PayPal and ships the item, and then after a while the buyer says that he never receives the item and request to refund his money.
1) Is there any warranty from PayPal Payments Pro?
2) How secure these transactions by PayPal functions to assure both buyer and seller?
3) Do PayPal Payments Pro keep the customers info in order to keep tracking of the items sold and a customer listing for future marketing?
Thank you for any info.
