Wow. I am from New England and I have to say that for the most part I shop at Market Basket due to the proximity to my home. When I am closer to suburbia, Roche Bros. for meats, Hannafords for variety of products vs Market Basket but I can never get enough of shopping at Whole Foods! I am lucky that I have many farms nearby my home so most of my shopping is done locally. Nothing like fresh milk,eggs, fruit, maple products, veggies, homemade cheeses and sometimes I can even find fresh smoked meat.
I live in the middle of Cape Cod and we do not have a Whole Foods although it was rumored that one was going to take the building formerly occupied by Borders, near the Cape Cod Mall. There is a Trader Joes near the mall. They seem to do well.
