The Thermos Stainless King 16-Ounce travel tumbler is down to $17.99 as part of an Amazon Gold Box sale. Before today it was selling for as much as $25 and regularly sells around $22. This price is the lowest it has gone since Black Friday and only the second time in the last year it has dropped below $20. Only the Midnight Blue color is on sale, but Smoke is also down to $19.99 from $25. That version drops in price a lot less than the others, so that's also a good deal.
The Stainless King uses vacuum insulation technology to retain temperatures, whether what's inside is hot or cold. It can keep liquid hot for 7 hours or cold for 18, and the double walls prevent your hands from feeling it either way. There's a built-in tea hook for tea bags, and it's designed to fit most car cup holders. It has more than 7,400 user reviews giving it 4.4 stars.
