What are the five most deceptive pricing practices?

The five most deceptive pricing practices include bait-and-switch tactics, where a low-priced item is advertised but replaced with a more expensive option; hidden fees that are not disclosed upfront; price anchoring, which involves presenting a higher original price to make a discounted price seem more appealing; promotional pricing that misleads consumers about the duration of a discount; and drip pricing, where the final price is gradually revealed as additional charges are added during the purchasing process. These practices can mislead consumers and distort their purchasing decisions.
