New federal regulations requiring companies to provide upfront pricing for services such as vacation rentals, hotels, and event tickets go into effect on Monday.

The new rules were initiated by the Biden administration in January and are being enforced under a new administration. They are set to take effect 120 days after being finalized in January.

The rule is intended to eliminate “junk fees,” the added costs that are tacked on when a consumer goes to checkout for a purchase. The Federal Trade Commission (FTC) said it expects the new rule will save consumers up to 53 million hours per year of wasted time spent searching for the total price of tickets and lodging.
