Because Walmart relies on their “Everyday Low Prices” to bring in customers, they don’t have sales. Instead, they have Rollback offers — permanent or temporary reductions in the retail price of an item. As you can see from the sign below, the original price is always shown in the upper right-hand corner. In this case, these green beans were 64 cents and are now rolled back to 50 cents a can.
Why does Walmart always feature the previous price near the rollback price? It’s down to a behavioral science principle known as Anchoring. To learn more about this principle, check out the Choice Hacking article here.
