Hi Irene,
OK, I've had the payment issue clarified for you. the PayPal issue, this is the one that I was most concerned about as anyone with a PayPal account can accept payments from anyone else with an account, no matter what country. However, this supplier does not accept PayPal payments at all, not even from US customers.
Regarding the credit card, they will only accept credit card payments with cards issued by US banks. So they will accept CC payments, but not with cards issued outside of the US.
So that does limit your payment options with this supplier. While we never recommend wire tranfers through Western Union or similar, now direct bank deposits for safety reasons, I can tell you that this supplier has been listed with us for the past 9 years and we have no complaints lodged against them for breaching payment expectations.
Now the bigger issue here may not be the safety of the payment options, it may be the cost to you. If you are going to do business, I would recommend bank transfer over money wire, but both are going to have transaction costs related to them. So those costs may well inhibit your profit making potential.
Cheers
