Hi. I have a question. I want to start selling phone cards on ebay and send pin numbers digitally, but I'm not sure how to enter the pin numbers. I plan on using a single "Buy It Now" listing with a quantity of 100. How do I list all the pin numbers on e-junkie if the Product Name (the title of my ebay listing) is the same for all of them since I am selling them together? Is this even possible to do? Any help would be greatly appreciated.
