...Now if I could only do that on amazon or at my local deli to buy beer, eggs, bread, and milk I would close down my Citibank account and go totally bitcoin. You hear me bitcoin DEVS, make it happen..... 
You can always invest in one of the several bitcoin debit cards that's available. In that way you can spend your bitcoin at your local deli. Bit-X and Xapo offers a card that is directly linked to your wallet [think there is others also] so you do not even have to 'load' the card beforehand, just swipe it and the amount comes off your wallet.
