Umm, doesn't a bottle of Pepsi cost more than $1?

At the typical rip you off "convenience" store, yes. At work, the machines are set to $.90 for bottles. In the past they used to be $.70, back when Compaq was paying a part of the cost.

So, a drink you pay normal price for, then a free song, not a bad deal. If people are going to buy a Pepsi just to rip the cap off for the song and not drink it, then yes, that is stupid.
