About 95% of my transaction is via Paypal.

I have searched many Payment Gateway also. However, it seem that Paypal 's fee is the cheapest.

However, Paypal will protect the buyer more than the seller. If you are not in USA. Once the buyer complain in Paypal, it is very difficult to fix but refunding

Please be careful. Always to ship out the item with tracking number that Paypal accepted .
