You can do a web search for gluten free
a lot depends upon what you are looking for and
where you live.
I order my bread from Canada where the maximum shipping charge is $10 from Kinnicknick and they have a great flax seed high fiber bread. They are also know for their pizza crusts, bagels and donuts, but since I'm always dieting I stick to the bread.
If you go to Amazon.com - their grocery section and search for gluten free they have over 500 items on the list (non perishable) and you can pick and choose what suits your fancy with that.
There are also a number of Celiac groups and chats on the web that are filled with experienced people with loads of good information to share.
one of my personal favorites
I've learned a LOT from this list.
