Any Legit places to Sell my Bitcoins for Gift Cards?

[dollaz]

I've noticed a few places where you can buy closed loop gift cards with bitcoins like cards you can only use at the particular store ex. gamestop, starbucks, target, ect

but I haven't seen any sites that offer open loop gift cards for bitcoins like Visa/Amex Gift Cards that you can spend anywhere that accept visa/amex..

is there a particular reason for this?

I ran into a few sites that claimed they did offer this but none of the sites are online anymore so it just seems weird to me. I been lurking these boards for a while and i haven't been able to find an answer to this yet any help would be appreciated..Thanks!
