I'm celiac, and the internets keep telling me that aldi has an amazing and growing range of gluten free stuff. Meanwhile TJ's gluten free pizza is a disaster and they keep discontinuing other things I could once get there. Which is annoying since they're basically the same company.
Are you a home cook, or do you go out mostly? My wife has celiac, so I've gotten pretty handy with GF cooking in the last couple years (mostly completely grain free, recently). I actually like it quite a bit. I don't really miss anything that I can't cook, and I find that I tend to view bread as a space filler a lot more than I used to. TJ's can eat a dick, as far as I'm concerned. I think the best thing for people with celiac is to spend as much time as possible in the produce isle of an actual good grocery store (or farmers' market, obviously).
