Trader joes has an interesting business model. Some of their stuff is really pricey, but some of their stuff is a really good deal. Gr8 Tortilla chips, gr8 taquitos.
I think the meat is pretty fairly priced. I usually get chicken thigh for 4.99lb. The big chunks of meat (roasts, etc..) are a bit expensive $20-$30. Only frozens I buy are vegetables. Buying anything in a box in a frozen section is dicey.
