We're in Wegman's territory and they do seem to have the best selection by far. Canyon Bakehouse is her go-to option. Also, Aldi has some very good products. Overall, she likes them better.
She found a woman in Bethany Beach, DE with a GF commercial kitchen in her house. She would supply the local health food stores in the area. She was phenomenal, but it seems she only bakes batches now and doesn't do personal orders. Her stuff goes the first day it hits the shelves. That is the "holy grail" bread. We would buy 10 loaves and freeze them.
This below is her favorite restaurant, if you're ever in NYC. Small, but very good and very safe. They also have a café/bakery down the street.
