I know a lot of people are using BTC to get USD/EURO...etc

I use mine to buy video games for Steam.

Here are three sites that use BTC as currency and have good deals.

http://www.steambits.com

And Humblebundle has really great deals. This week is comedy stuff not video games though. http://www.humblebundle.com

Where else can I get games for BTC/LTC?

And also, does anyone sell groceries for BTC?
