Don't know why more stores don't do what Costco does. Put (an) employee(s) at the exit door and have customers show their receipt and check to see if it matches the items going out the door in your cart.

Costco has a much higher average ticket, and much average cost per line item.
So for a dollar store to check things at the exit would eat a MUCH much higher proportion of sales to have someone manually check them all.
The shrink presumably is still far below the level that would make that worthwhile.

Having very low staff costs is one of the prerequisites of the economics of a dollar store.
Originally that extended to not bothering to mark things with prices, nor even scan them at checkout--at a true one-price store, the goods merely had to be counted.
Later on they because some of the most sophisticated retailers out there, with big data centres running Retek systems, because the movement analysis data were so valuable, so scanning was needed.
