That's likely to put a serious dent in profits, which are already razor-thin -- for Walmart's last fiscal year. This at a time when overhead costs are rising after an the number of items Walmart carries flopped and the company decided to restock thousands of items.
If the item doesn’t have another store name and price list under the Walmart price then Walmart is the lowest price for this week. If the than that store is lower than Walmart. You may also see similar items that Walmart may not carry that particular brand or size but if you have that other store close to you that is the lower price.
