Also to add, the things you already have listed all state free postage

So if those sell, you can't ask the buyers to pay for postage after the fact

Given the number of fake/knock off USB drives that are on eBay by the bucket load, you may have a hard time selling things like that since buyers are becoming less and less likely to risk if the ones they are buying will be real or not

And that could be especially true for new seller of them who only offer stock photos
