Help!! Gluten free is sooo expensive!!

My son just found out that he’s gluten intolerant,one loaf gluten free bread 200 grams (about 1/4 pound) is $6.00!  Holy cats?!  Any one have any ideas?  Could we use flax bread instead? i know bread is just one level of the problem.  I really need a little assistance in figuring everything out.  I’ve not gone through the other cooking sites I visit.  I think they’re a bit clinical.
