when i had my megadrive i always went to the market in the near by town to buy pretty much all my games (don't think i bought a new MD game) i could usually get them for about £10-15....and i think the most i paid was £25.... bare in mind though that they are proper second handers, in that they had either no box or a ruined box, and in fact were probably 3rd or 4th hand.
When i had my N64 i usually got games from a shop called Games2u in Huddersfield, which was primarily second hand games.
My GC i think i have 3 or 4 second hand games.... 2 of them i got from Blockbuster, but the rest were new because for some reason i didn't like the idea of second hand discs....I have always been quite precious with all discs like CDs/DVDs etc, and i have seen what a lot of people discs look like even after only a month or two.
