My website allows people to list items to sell to other people. Here is an example:
Seller lists item for £20 with £4 postage. Buyer buys the item and pays. I get 10% of the seller's item price, so £2 comes to me. Buyer receives £22.
The problem is with PayPal fees. I get charged 3.4%+20p on my £2 commission, which is fine (leaving me with £1.73). However, Seller is charged the 3.4%+20p as well. THIS SHOULD NOT BE HAPPENING! Should it? Why is the seller charged as well as me?
I need a developer to sort this out by contacting PayPal and talking it through with them.
