I thought i give it a shoot and see if i can win a psv. I already pre-order mine, this is just for fun. I went to taco bell and get a $5 plus tax inside the box psv. I notice they printed the code right on the outside of the box. Anyone working at taco bell can easily copy the codes and used them their self. Also i think it would be really easy for the person who delivered the boxes could of just peek at the codes. If sony was to do this, they should of make it scratchable. I heard of ppl using their codes and it said its already been enter. BTW i did not win.
I bought two of those $5 boxes, and I noticed how similar the codes are to each other; just a letter and number different from each other. So people might just be generating their own codes by trying all kinds of crazy combinations.
The idea of that just kind of discourages me from trying to win. No wonder why other people are reporting that their codes aren't working. It's not just the fact that codes are printed right on the boxes themselves.
