Where can I find these for my boyfriend?

Ohkay, so my boyfriend absolutely loves Monster energy drinks. And I saw at the gas station that they had a huge cardboard cut out of a monster can, I mean it was huge! At least 4 1/2 feet. And I really wanted to get him one for our anniversary, but I have no idea where I would find one at? Any Ideas?? Also, he's a marine, and a week or so ago, I accidentally burned a little hole in his flag with a cig ): And I feel really bad, because he was so mad, because he's in love with the thing. Where could I find a marines flag? And how much would it cost? Thanks (:
