I just went to Grand Mart for the first time and loved the produce section. So many vegetables I've never seen in a regular grocery store, and everything was so fresh and cheap! I bought a few things but now I am wondering - how do they sell things for so much less than other stores? What I am really wondering - is there anything wrong with it - i.e., is it grown with worse pesticides or other gardening practices that make it less healthy? Or is it just cheaper because they have less overhead (less fancy stores), or are the other stores marking things way up? Or something else?
