My experience, from shopping in Walmart quite frequently, is that they are highly disorganized and un-nimble. I guess this affords the opportunity for persistent arbitrages. For example, my local Walmart supercenter routinely runs out of certain products (not usually the same products). Sometimes it feels like GUM (An iconic USSR department store in Moscow). I gone shopping and found them missing any kind nutcracker ( a basic utensil), grapefruit juice, landscaping mulch, etc (many more examples). At the beginning of August the garden center had already moved out all its mulch for the year and filled the shelves with de-icing salt lol. The people who run the place do not seem to understand opportunity costs: they lost a sale in me and I am pretty sure nearly no-one is buying de-icing salt at the beginning of August. This is a northern USA store but where I live the weather is in the 60-70 through October: grass still grows, gardens still can be mulched. The stores are overstaffed with floor people (seemingly wandering around Lord of the Flies style) but not only 3-4 of 20 checkout lanes are open at a given time. Nearly every single canned good is dented or has a dirty lid. Their self checkout POS run on Windows 7 (lol) and update firmware automatically when they reboot which is hardly ever but for a power outage. If there are intermittent power outages in a storm a POS could reboot on the first outage and be bricked on the second one while updating firmware. There are so many opportunities for improvement with Walmart but the capital cost of a competitor entering the industry is so high. I am not sure if Amazon can be a real competitor (I think they largely serve different sets of customers).
