$100 eGift - 50 BTC at Bitstamp Rate
This confuses me. 50 BTC for a $100 eGift card? You probably mean $50 of BTC for a $100 eGift card?
Anyway, considering you have zero feedback/trust, I'd be willing to buy it and release the BTC from escrow when it is completely spent. Otherwise, AFAIK, there's no way to prevent you from also spending it or reselling it to someone else in the meantime.
In all honesty I was too lazy to put control shift for the cash sign which I will correct. But anyways, you have full rights to replace the gift card number and PIN. Take the gift card off my hands, and make an account via Starbucks.com. You can purchase a $100 Starbucks eGift Card and mail it to yourself paying through the gift card I provide you. Better yet, I can do that for you if you'd like. This way there is absolutely no chance for respending or reselling which is not my intent but I do understand your concerns.
Thanks
