Full-price merchandise almost always ends in a familiar rounded figure, while clearance tickets end in unusual digits. The endings are a code, used internally and readable by anyone who notices the pattern.
Full price and clearance use different endings
Regular retail prices in the United States overwhelmingly end in nine, a convention old enough that shoppers read such a price as ordinary rather than as a bargain.
Clearance prices are deliberately given different endings, commonly one, three, seven or a round zero depending on the chain.
The change of ending is the signal. It marks the item as reduced without requiring the shopper to remember what it originally cost.
The ending encodes the markdown stage
Chains that run several rounds of reductions assign a different final digit to each round, so an item's ticket shows how far through the schedule it is.
Staff use this to identify stock that is due for the next reduction and to spot merchandise that has been on the floor too long.
Regular shoppers learn the same code, which is why some know from a glance whether an item is likely to be cut again or has already reached its final price.
Endings also separate permanent from temporary cuts
A temporary promotional price and a permanent markdown are different decisions, with different accounting and different intentions.
Using distinct endings keeps them apart on the shop floor, so a sale price that will revert is not confused with a clearance price that will not.
This matters at inventory counts and at the end of a season, when the two categories are treated very differently.
The system does not carry across chains
There is no industry standard, and each retailer chooses its own convention, sometimes changing it between departments.
Advice that a particular ending always means final markdown is therefore only true within one chain, and often only for a period.
What holds generally is the structure: a shift away from the normal price ending indicates a reduction, and further shifts indicate further stages.
Why the last price is not always the best deal
An item at final markdown is at the lowest price it will reach, but it has also survived every earlier reduction, which is information about how few people wanted it.
Sizes, colours and condition at that stage are what was left after everyone else chose, and clearance items are frequently excluded from returns.
The endings tell you where the item sits in the schedule, not whether it is worth buying, and the two questions are easily confused.
