Well, since folks started naming MSC's.. TheSource still has grocery shops near me, but they are the company that got strange a couple years ago and I refused to do shops for them anymore. I've been doing the grocery shops through Marketforce, they are simple and I grab all the sandwich shops I can. But they went away. Confero advertises grocery shops in my area, but the ONLY one they list in my entire state is 60 miles away.
Back in CA I suspect there are lots of grocery shops, between TheSource, Marketforce, Alta, and that other one that uses the Prophet platform software (can't remember the name of the company, I assume I'm still signed up with them, but they don't have any work for me here), there are plenty of grocery shops to do.
I most certainly miss having all the Hispanic and Asian grocery stores close by. They are few and far between here, and nothing like the ethnic stores in CA.
