I was at the deli at our local Giant Eagle, asking about gluten-free deli meats, and the lady behind the counter pointed to the countertop where there were a whole pile of pamphlets (nicely printed in color, several pages) about all the differnt gluten-free products Giant Eagle carries and in which section of the store to find them!!!!!!
The down side--not every store carries every single product listed. They didn't have he first 2 deli meats that I requested. But it's a start!
I suggest that everyone ask their local grocery store if they have such a pamphlet, and tell the managers that other regular grocery stores are doing this!
