For what its worth
Vendors-Make many of us happy
It isn't easy (for me) to read what is on the end of the box nor railroad nor have to stoop on the floor, or in cardboxes with not visible end info
Create a list(s) of what you're selling
Make it available to the public at your booth
For example, like the info on the end of a box-
I would like to see supplier, part number, railroad, item description ( price will be on the box)
Ex: If I want just K-line I can look at this list and right away decide if there is something there or move on
You the vendor can use this list to cross of what is sold
