Mattress Hotel
Another business idea, for a hotel.
In a location that gets lots of non-international tourists who stay at least 3 nights, for example the Gold Coast in Australia.
Have a mattress showroom attached to the lobby. Test drive beds in the lobby, and choose the ones you wish to trial in your hotel room.
Hotel staff switch out the beds each day.
When you leave you get an offer to buy your favourite bed, guaranteed discounted and delivered to where you live.
The beds are not visibly branded, so you are not influenced by brand, and you cannot research prices elsewhere 🙂
Note, this has been tried on a single option basis before, with success:
