I was the same way in college. I got my studen loan money and dropped in to pick up some ammo and spied a nice shiny AR-15 on the wall that they had just pulled out of the box. Price was $850.
This was spring of 1994 when the assault weapons ban was about to go into affect. You couldn't even find primers, ammo, everything was sold out. Needless to say I walked out of there with just enough money to make a down payment on tuition and a nice shiny pre-ban AR.
