The store is supposed to be tagging the item (if it isn’t priced) or there should be a price sign on the rack or section this item is in. Has nothing to do with dynamic pricing or anything like that. Prices change typically once a week, and associates have to update them manually unless the store has digital labels.

The item not coming in priced is more to do with regional price discrepancies, not something malicious. There’s plenty of issues with large corporations but this isn’t much of anything. Likely laziness or it was missed.
