I would be willing to bet that Woodman's is about 75% the price of Hi-Vee or Copps. Absolutely huge selection of items. This is where I go for most of my groceries.
Minor Complaints:
They don't have ready made meals and more specialty-type foods but I forgive them because it is so cheap. The liquor store has a very large selection and is all on the East side of the building in a separate area. So if you are buying food and booze you are going to get rung up twice, which is annoying. Also sometimes they run out of produce items but that only happens to me on the weekends.
