I wondered whether International Gourmet, a foodservice company, stocks the 6-in-1s, so I called their offices in Virginia to get a telephone number for their Atlanta operation. IG does not sell to individuals but they may give you the name of an account from whom you may be able to buy pizza ingredients. As it turns out, it appears that IG does not sell the Escalon products but they do sell the Stanislaus products, of which the Tomato Magic is very similar to the 6-in-1s. If you are interested in following up on the matter, the person you would call is Craig Coleman, at 404-201-1746. The basic office number for IG in Atlanta is 404-201-4663. I believe IG also sells the Caputo Pizzeria flour and most likely other flours. It's also possible that different locations of IG carry different products, so the product mix for Atlanta may be different from the other locations.
Good luck and please let us know if anything pans out if you decide to call IG.
