This is correct. I get emails from a company called Webstaurant. When the shelves were bare we simply ordered the larger commercial rolls from them. They don’t fit into your typical residential wall mount. It’s a two-handed unroll operation but, we have plenty on hand.
I don’t know ... I just looked at the Webstaurant web site. Every kind of TP was marked as “out of stock”. Every single one!
Webstaurant is one of my favorite vendors. They have a lot of stuff that’s useful for home purposes.
