Where can you get used PS2 games? There are tons of places you can find the games, both new and used. Here are my favorites:
GameStop Stores - If you’re lucky enough to have a GameStop store where you live, they always have a bunch of used games, and for cheap. Also keep an eye out for their ‘buy 2 get 1 free’ sales, which they run quite frequently. They have plenty of new games, too. Just this one store can easily keep you in new (well, new to you) PS2 games for a long time on a tight budget.
EB Games - There’s also EBGames.com, which is owned by GameStop. Their websites look very much the same and I think they run off the same inventory.
eBay - You can always get on eBay and shop around, and you can sometimes find some good deals on ps2 game lots, which is where somebody is auctioning a bunch of games in one group. I’ve found some great deals this way, and the price almost always ends up being cheaper than if I had purchased the games separately. You can also usually find some great deals on PS2 units and other accessories from gamers that have upgraded or no longer play.
Amazon.com - In the past couple of years, I have used Amazon.com to buy and sell used games more than I have with eBay because on Amazon you can see the actual sale price and don’t have to worry about bidding and all that. I’ve found that Amazon sellers often have better prices than what people are bidding on eBay, so you should definitely compare prices before you buy. The only downside is that Amazon only sells individual items, so you can’t find any game lots.
