It may almost be the head of the summer, but it's never a bad time to start thinking about stocking up on things for the winter. Winter goods are often much cheaper right now, and this 12-pack of pairs of hand warmers from Heat Factory is on clearance at REI. That's 24 total hand warmers for just $1.93. That's 83% off or just about $0.08 per hand warmer.
If you order online, you'll have to pay for shipping unless your cart total is over $50 -- consider one of the REI deals below that are still going on. Of course, you can also opt for free in-store pickup at an REI near you.
