Hey Bud, I recently sold my PS3 320GB and games and actually didnt make out too bad.
First thing, DO NOT sell as a bundle, people will offer you peanuts.
Make a list of all your games, check online second hand game prices and make yours competitive (I say R20 lower than the average price). Once you have a list and happy with the prices, advertise them on sagamer, gumtree, OLX, etc. Maybe offer a discount if someone is willing to take multiple games.
Sell your console with any accessories for a set price and maybe throw in a couple games (preferably the oldest ones in your collection)
It will take time but you will eventually make some decent money.
