What kind of Greek Yogurt?

I have seen yall at one point or another discussing greek yogurt. What kind do you get? Can I get it at Walmart (making a trip tonight)? Does it have a different taste or texture?
Thanks in advance for the help on this!
Feel free to tell me how you make your favorite greek yogurt recipe!

This is the first I have heard of it.  If you find out anything, let me know.

Hi,

I just found out that Giant sells it.  We don't have a Giant store up here so I can't confirm it.
