E-junkie is not a payment processor, so we never handle any actual payment funds from your buyers at any point. Instead, buyers would pay you directly via your chosen payment processor, such as PayPal. In order to use our shopping cart and other features, you would need to have an account with at least one of the independent payment services we support:

E-junkie's flat monthly subscription fee covers your full use of E-junkie itself to sell online for the month, but this does NOT cover any fees payable to third parties for their own services, such as the transaction fee that PayPal withholds from any payments you receive through them.
