My experience is that most Walmarts in central NJ are not Supercenters and generally only carry limited groceries (no meat or produce). Walmart might have lower regular prices on some shelf stable products, but Shoprite wins hands down in terms of best prices when you consider sale prices. Wegman's is a private chain that originally is from upstate NY. They have seven stores in NJ (several compete directly with a VLGEA Shoprite), so they may prove more of a competitor than Walmart if they continue to grow the store base in NJ.
