how about giving customers a choice? you could continue to use their own payment system while i could use PayPal. nothing would change for you, but Amazon, PayPal and I would all win.
Amazon would need to create a paypal account and pay 1.9% of all their transactions + nominal fee per transaction.
The standard rate for receiving payments for goods and services is 3.4%.
If you receive more than €2,500.00 EUR per month, you're eligible to apply for PayPal's Merchant Rate - which lowers your fees as your sales volume increases. Your fees can be as low as 1.9%, based on your previous month's sales volume.
I'm sorry but I just don't see how Amazon would "win"
by giving Ebay a few millions. Because considering the amount of stuff Amazon sells world wide you are talking about millions, not small change.
