In my area Walmart is not the 'low price leader' anymore. In fact, they are price competitive with Albertsons/Safeway and Fred Meyer (Kroger). Whom all 3 stores are EXPENSIVE. I don't shop at Fred Meyer, but have seen some of their flyers. They and Albertsons/Safeway sometimes have some really great sale prices on certain items. That is the only time I shop at Albertsons/Safeway, just to get those sales items.
One thing I've noticed at Walmart....and I think someone mentioned it in a previous post.......that pre-plandemic, there were more store brand items and sold in the larger sizes. But now there are fewer store brands and only small or 'regular' size items, while there is plenty of the name brands of regular sized items.
One item for instance......1 gallon jug and quart jar of Great Value mayo before 2020 but now they don't have even the regular size jars. Only Best Foods/Hellmans or Miracle Whip. No gallon jugs at all.
Another thing I used to buy was the 3pk of Great Value Shells & Cheese.......now they only have the 3pk in Kraft brand. You can still buy the individual boxes of both.
You would think Walmart would make better profit off it's own brands, regardless of package size, since the name brands have to make their profit margin, plus % to the retailer.
