Walmart Stores U.S. averages $5.7m/month gross per store. Years ago I worked at a tiny CVS that routinely hit 50k in a week.

Revenue figure comparisons are not meaningful if the gross margins are not similar.

For most grocery stores, the profit margin is around 2-3%. In other words, if someone steals a pack of cigarettes they have to sell $200 of groceries to make up the loss.

Software revenue margins (particularly web services) is much higher than the margins enjoyed by your local supermarket.
