I had not been to or heard of Grocery Outlet stores until I moved here to CA. I went one time and I liked it. I describe it as being like the Big Lots of grocery stores. They have a bit of everything just like a regular grocery store but their products are overruns, package changes, stuff from stores that have closed, etc, etc. You have to watch the dates a lot of the items are very close dated or expired. Some are nicer than others. We have one close to us that is just "trashy" and I dont like to go to that one by myself.
I did recently get the huge bottles of Gatorade for .99cents which is a bargain. The big bottles are very $$$ usually. They were close dated but as fast as we drink it, it didnt really matter. For me its just like big lots, sometimes you find stuff and sometimes you dont, but when you do see something, you had better grab it, cause it probably wont be there when you get back. They also have a website where you can play a word scramble game and they'll send you a $2.00 coupon. I do that about once every couple months or so, they've had the same words up there for the 2 years that I've been playing it...
