Amazon offers the Duck HD Clear Heavy Duty Packaging Tape 6-Pack for $11.37. Checkout via Subscribe & Save to cut that to $9.66. With free shipping, that's a buck under our January mention and $2 less than what you'd expect to pay for this at a local retail store today. The adhesive bond strengthens over time for a long-lasting hold, and meets postal regulations.

Note: Be sure to cancel Subscribe & Save after your item ships to avoid being billed for future shipments.
