You could probably make a business doing this, and hopefully that would make n very large (although presumably people won’t wait forever so you will probably want multiple sets of products). You could also let people keep whichever product they like best and return the rest (and then you replace their favorite).
You can sort-of already do this by just buying all of the products yourself and returning all of them you don’t like, although that hurts your favorite business since they usually can’t sell returns for full price. Making this “how the business works” should help customers (since they won’t fell bad about trying all of them) and hopefully the business too (since it will be known that most of the products are used and that’s ok).
isn’t what you suggest basically just rent to buy type of bussiness?
There may be some minor differences since people typically rent the product they think they want instead of renting all of them, but I think you’re basically right.
