He is still selling them. Also sells the empty paper rolls..Seems a little odd to me. We all learn from our mistakes Steve. Hopefully you can get an refund through paypal if you paid that way.
Or, If you haven't already left feedback, you could go back to the seller and request a refund. That worked for me when I schooled on this lesson. Fortunately, I bid cautiously and only overpaid a little (that 3-cent nickel on the end was just too tempting..). The seller would, I'm sure, prefer to offer a refund than receive negative feedback. Or, if you can stomach the loss, leave that feedback as a warning for those that are at least diligent enough to read it.
