I have a suggestion for ABNB, you should launch an affiliate program so that hosts can get discounts on common items such as linens, towels, mattresses, pillows, etc.
When purchased through the affiliate program, the host would get a certification on their listing that states they are providing an abnb experience.
Hosts would be encouraged to purchase from the affiliate program for price and reputation.
The idea comes to mind that certain high end hotel chains sell their mattresses/linen And etc. retail.
