Well, we love Walmart. We do the bulk of our shopping at BJ's and Costco, but we go to the King of Prussia Walmart a couple of times a month. It's the only other grocery store we regularly patronize. We buy the same stuff every time we go. Always get yogurt and a few other specific items not available in the warehouse clubs. We find Walmart grocery prices the same as the sale price in the grocery stores. No, they don't double the coupons if we have them, but we save on impulse buys that we always have on the loss leaders in the grocery stores.
Store is clean and staff friendly and helpful.
