@Bradley153 If a host uses smart pricing, the host isn't practicing bait and switch. Smart pricing is automated- the host just sets the minimum price they will accept and the program does its thing. The host might not even realize that the price for your inquiry dates changed unless they check their calendar prices multiple times a day.
When people want to fly somewhere, and scout around for airline tickets, if they don't book it right then, but go back sometime later (maybe even 5 minutes) to book a flight, the price has often changed and no one considers that to be bait and switch, it's just how the business works.
So hosts who use Smart Pricing aren't trying to scam guests- they just find it more convenient than having to scout what the competition is charging for various times of year, holidays, major local event weeks, etc.
And it isn't something most hosts would concern themselves with, as while you might like to send an inquiry before booking a place (I would, too), the majority of inquiries hosts receive never turn into bookings, even if the price doesn't change- most guests who send inquiries are just looky-loos, may have sent out inquiries to 10 different places for the same dates, or are asking to break the house rules, like if they can bring their dog to a No Pets listing or bring a group of 10 to a place that accommodates 6. Most inquirers also never respond to the host's return message- not even to thank the host for a prompt reply. They just disappear, never to be heard from again.
So if the price changes on you, just ask the host if they will honor the price that showed when you inquired- many hosts would. The host just has to send you a Special Offer to accept, with the original price.
