Weight detection mechanisms for cashier checkout terminal are provided. When a transaction by a customer concludes at a cashier checkout terminal, a check is made to determine if a product was left behind on a baggage unit associated with the cashier checkout terminal. When excess weight is detected on the baggage unit at the conclusion of the transaction, one or more alerts are generated to raise awareness with the customer that the product has not been retrieved by the customer from the baggage unit.
