Here are step-by-step instructions:

Step 1:  Buyer will see the asset within their "Open Auctions."  Note:  If it's pending seller approval, there will be a note.

Step 2: The buyer checkmarks the asset(s) that they want to pay for, and then they click "Continue to Checkout."

Step 3: The buyer selects the payment method (if applicable).  Some sellers do not allow electronic payment (wire, credit card or PayPal); they must pay the seller directly.  This is explained within the "payment instructions" of the buyer's certificate, too.

Step 4: This is what the buyer sees if they select "Pay with Credit card."

Step 5: This is what the buyer sees if they select "Pay with Wire Transfer."
