One strategy to fight this is to offer rewards programs and/or credit cards with special perks. Retailers you've pointed out in other comments do this -- Amazon has a credit card[1]. Target has one that gives you 5% off purchases at Target. Also airlines and hotels do points/miles and credit. Without them, people would only choose the best price every time.

Does AirBnB have enough regulars to make those rewards programs worth it? Do travel-weekly business people use AirBnB? If not, it's like being given the buy-10-get-one-free sandwich card at the deli you go to once a year.
