Sam's Club offers its members the Scotch Heavy-Duty Shipping Tape 6-Roll Pack, model no. 3850, for $17.93. Choose in-store pickup to drop it to $10.37. That's the lowest price we could find by $23. (We last saw it for $37 shipped, but it was bundled with $30 in rewards.) It's about 20 times stronger than acrylic tape.
