Best website to sell used games on?

I'm having a clear out of my room and I've found a bunch of old gamecube, gba and xbox games. A couple of them are unusual jrpgs that I reckon I could get some good money for (I've seen some CRAZY prices on amazon for used copies). Whats the best website to sell this stuff on? (Bare in mind I live in the uk)

ebay.co.uk is a solid one there. Pretty sure there's a bunch of hobbyist forums too (cheap ass gamer maybe?).

Hmmm interesting, I'll have to give it a look

eBay will get you the highest prices, though you have to put in the lion's share of the marketing work preparing the sale page/description.

Amazon will get you a little less depending on how many copies are bought/sold on average, but you can just put your game up and wait for a sale.
