Libraries get a contract discount ordering supplies from Demco, hence their pretty loyal usage of that brand. 😉 Flat msrp is $$ for demco vs scotch, so here's the scotch book tape if you're interested. Not affiliated, just the link. It's really almost exactly the same as the demco one (I've used both and I use scotch for my personal stuff.)
