I think the best deal I ever got was many many years ago. So I was the really young geeky girl who frequented the local game shop (I forget it's name) on a weekly basis because it was essentially next door to the grocery store my parents went to. I think I was way too young to comprehend that loaning games was a money sink (I should have bought them, durr but it's cheaper to rent right? Unless you like the game!) Anyhow, so I was there, and someone was at the counter and pondering aloud whether it was a good idea to buy a Genesis for their kid, would they like it, was it a good system, etc. So being the silly kid I was, I go up and expound on how totally awesome it was, I wish I had one, my friend has one and it's so totally cool, etc. So I helped make the sale, and after the parent bought the system and left, a few minutes later the guy at the counter (must have been the owner) gave me a few NES sports games for freebie. Granted, they were in bad shape (so I gave them a good cleaning with my cleaning kit) but hey, it's freebie, whatcha expect?
lol I still have my NES too. Still works!
