So, what can you buy these days for a dollar? A small pack of gum? That's do-able. A candy bar? Certainly. If you've got it in quarters, amassing a four-strong army of aliens packaged in plastic eggs can be done. Besides those sorts of options, the dollar doesn't buy a whole lot unless it can be spent on the Xbox Live Indie channel. In that case, a hundred shiny pennies can be exchanged for one sweet little shooter.
