We need a national law and FTC teeth to say "The price advertised is the final, final, all-in price you pay" and the right to demand the product be delivered at that price if you were advertised a price. This should include limits on dynamic pricing which "whoops the price changed for the worse between when we showed it to you and when you drove to the store..."

As an example related to Renting. I once saw a place advertised for rent at a price in my budget. Booked a showing the next day. The dynamic pricing increased it several hundred dollars above my budget. The land lord (company) would not honor the price I booked my showing at. I immediately left saying I do not do business with such dishonest practices.

We also need to ban using the renters as a captured audience for products.

Edit to add:

When I last rented from a big corp I got:

$5 a month semi-mandatory fee on automated payments through their app (as if them handling a check would actually cost them less than an automated payment)

Mandatory internet package through a single provider.

"Resort fee" of $30 a month which was more than the cost of a proximal gym providing 10x the equipment.

Move in charge - $50 just to move in as if I was going to rent but not move in?

Move out charge - $50 just to move out as if I was going to not move out when my lease ended?

I also think rent raises after a year's lease should be limited . Why is the 13th month 100% more as if I'm not a long term renter? It makes some sense for short term rentals but this isnt a 1 month rental, it's a 1 month extension to a long term rent.
