Big M Supermarket is a convenient local store with a good selection of groceries. They often offer sale prices that beat Walmart and Aldi, especially on national brand products. The deli counter has grab-and-go options, and the fresh meat case is well-stocked and looks great. Customers appreciate the courteous service at the registers and find the prices fair, especially for special items like prime rib roasts. The store also features a great beer selection, Finger Lakes coffee, and affordable Adirondack soda. While the store provides quality products and friendly service, some wish they carried more gluten-free options. Overall, it’s a reliable place for shopping and quick meals.
