I'm looking for a single roll of 4910 1/4" x 36 yard. I've seen prices very widely from $29-90+USD for this one roll. I think the $29 is a pretty good deal judging from what I've seen but I was wondering if it got sweeter than that. Are there any magical stores out there that I should check?
4910 1/4" for $29
EDIT:
Also, I've been seeing pics of tape dispensers with an edge guide to quickly and perfectly lay the tape along an edge. However, I've searched dozens of industrial supply and other sites without being able to find anything similar. Perhaps it was a custom job? Anyone know?
