I understand what your saying. I was hoping to sell it for a 10% discount. If I can't find anyone interested in a week or two who are interested at 10% maybe I will buy a high valued item and resale on ebay.
I am really not familiar with the ebay market for things that are radially available however I would think that items would generally sell for discounts on ebay as well. I imagine that discounts on ebay would be more then 10% (probably somewhat inline with the discounts that gift cards sell for on here).
You can potentially buy things on amazon via purse.io and get bitcoin. This would solve your timing issue however you generally have the same kind of discount as above.
I know that grue is/was buying amazon gift cards @ 85% of their value however I don't know if he would be willing to take on your balance. He also wants to see proof that the gift cards were purchased via legit means
