I looked around and was horrified at having to pay $3 (or more) per roll for packing tape. I had been using some 3M / Scotch I had for years and finally that pile ran out. Wrapping packages for online auctions is the primary function in out house. I noticed it's not as thick or as sticky as the 3M/Scotch brand (which Staples sells too) but at far less that 1/2 the price per yard I could easily use twice as much and still save money. In fact I do not use more than I did as the 3M is actually overkill. This does fine and I found the double size rolls were the best price point value compared to every other choice in Staples - including all the other online sources I looked at. Even cheaper online sources ended up being more per roll than Staples once you factor in shpping costs. I estimate this as being about 3/4 as sticky as the 3M heavy duty tape (again fine for 99% of uses). If I had both types of tape I think I would use 20 rolls of this tape before I used one roll of the heavy duty 3M tape.
