Let me know if interested, I run a business so I would simply pay for inventory using the card, however to prevent you from trying to chargeback the payment and all that crap I would need the card in hand plus a week for the funds to clear once the card is used.
I know this might some like a hassle of a trade and might be a low offer but it seems to be the highest and best one you've gotten so far. If you choose to decline this offer I wish you the best with using/selling it.
The card was bought for cash, and can't be charged back or invalidated. If I was trying to scam you, the worst I could do would be send you the card, then try to spend it before you did.
Also realize that I can go to the store and buy $500 worth of stuff with this card, so I'm not jumping at the opportunity to get $435 for it.
