Where do hotel purchasing managers usually find "consumables" for purchasing rooms?

Purchasing this kind of thing, I think the market is not very reliable. If you want to find a professional website, you will find many websites when you look for room consumables on the search engine, which are basically synonymous with prefixes such as low value and room, or disposable hotel supplies. There are still many purchasing websites for hotel catering. If necessary, you can use keywords such as daily price to search.
