Dollar Tree, Inc. (DLTR)

A single price is not a marketing trick but a way of operating: the buyer selects goods to fit a set price rather than setting a price to fit the goods. That simplifies everything from supplier negotiations to the checkout, and turns the shop into a place people enter to see what turned up rather than to buy something specific.

Inflation broke that construction: holding the old price became impossible, and the company had to raise the level and add more expensive items. The transition is risky — it dilutes the very promise that brought people in. In parallel the company disposed of a badly bought chain in a different format. It pays no dividend but buys back stock.
