When we grocery shop each week we know we have 3-4 places we're going visit: HEB (south Texas grocery chain), Walmart, Sam's Club and a local dollar store. We've compared all the normal items we buy (size, weights, flavors, prices, etc) so we know which place to get which stuff for cheapest.
Everyone says Walmart is cheap, garbage, for scummy people, etc.....LOL.....it has plenty of savings and quality foods. Their own line of bread (split top white and wheat) is excellent. The store brand "Crystal Light" is awesome, their store brand milk, oj, etc....all good stuff. Their produce is hurting though....that we get from HEB (our local grocery chain....always quality). The meats it's 50/50. We buy from whomever has the best deals that week. Although often you can buy quick sale cuts of steak, roast and pork from Walmart that are great. Chicken is often HEB or Sam's (despite Sam's and Walmart being one and the same essentially). Toiletries it varies depending on sales, but there's no scam at Walmart. I've purchased packs of chicken breasts from Walmart and HEB that were roughly the same cost and size and there was no funny business.....8-10lbs was roughly 8-10lbs. Cooked the same meal week over week with the similar chicken from each store and it yielded roughly the same amount of food.
Hey some folks like to pay $10 for the same thing that costs $5 elsewhere just because it's from "store A". A lot of these same folks pay $550 for a pair of blue jeans, designer tshirt and sneaks.
