Back when I was a kid, we (as in my parents) were pretty poor, and I would save my "allowance" for my mom and my garage sale adventures. Beings the SNES was only a year or 2 old at that point, I would pick up some really nice games pretty cheap.
For example: I picked up Final Fantasy 2 and 3 (cart only), River City Ransom w/box, and plenty of other NES and SNES games for $5 a pop. Hell my cousin GAVE me one of my favorite games, Chrono Trigger.
Kept me entertained plus wasn't a big expense to myself or my parents.
One of my friends had a lot of Sears and JCPenny holiday catalogs that actually had like a 20 page spread of just video game stuff. Was pretty cool to reminisce looking through it all.
If she still has them, I may scan them in and share them.
