Can you ship them within CONUS for 8.33333333 BTC?
No, sorry. I intend to do electronic exchange only by providing the visa.gowallet codes so the buyer may do with the funds whatever he wishes (load onto another card, spend online, whatever). You don't need the physical cards for that.
I need the physical cards to buy gas, and don't know of a card that will let you cash advance a Visa gift card onto it.
