I want to send hotel supplies to the hotel, but they have supplies. How can I sell them? Is it useful to distribute leaflets?

It's no use handing out leaflets. Handing out leaflets can only be a mass tactic. Take a chance. You can only find the right person with something better than others. Or price, or quality, and so on. Better than others. This has a higher success rate. However, hotels generally have special delivery personnel, and there may be family members in the hotel, so you should know the details of each other in a targeted manner. Then you will know how to target this hotel and how to supply it.
