Hi Matt,

The better listserv for this kind of question is tap-l. Go to
www.pira.nu and continue on to the main site. From the main site, you
can find a link to tap-l. First, read all about PIRA, who we are, what
we do, and why we do it, then subscribe to tap-l.

But to answer your question, probably 95% of anything you ever want to
find can be located in a McMaster-Carr catalog. Their website is great -
www.mcmaster.com

Go there and do a search for packing tape. Scroll down, and you'll see
Scotch #375 Carton Sealing Tape.  That's the stuff you want, and they
have it in a 3" roll. Currently, it's $6.44/roll. I'm close to their
warehouse, so if I order before 5, I have it in my office the next day.
Always. Well, except for welding rod, but that's another story.

Have fun,

Sam
