The Polish competition authority published a consumer-awareness message for World Savings Day about tactics that can encourage unnecessary spending. It describes examples including free-delivery offers that prompt shoppers to add more items, subscriptions that charge recurring monthly fees, and viral trends that pressure consumers to buy popular products.

The authority says these tactics exploit impulse buying, apparent savings and the feeling that another purchase is essential. It advises consumers to recognize these spending traps, stop responding to them and calculate how much money they could keep. The authority points consumers to its savings calculator.
