What do you mean, "you people"?
Just kidding, I'm not really sure what you're asking about, I'm assuming english isn't your first language? The post is a little jumbled, but strictly from your last sentence I'll derive that you're looking to buy console or PC games over the internet.
I do all my shopping at Gamestop, in store, but should they not carry something, whether it be rare or whatever, I usually go to Amazon.com. I like Amazon because it's quick and cheap, and it isn't as elaborate as ebay.
If you're wanting brand new games as opposed to used, I would still suggest Amazon, because if you shop from a dealer you're almost definitely going to either pay face value or more. Don't forget shipping either!
If it's a PC or next-gen console game though, make sure to check the official site because some games you can pay to download and save a quick few.
