Tanga offers the Contigo Randolph 16-oz. Autoseal Mug 2-Pack
in Latte/Watermelon, Latte, or Watermelon for $19.99
plus 99 cents
for shipping. That's the lowest total price we could find for the quantity in any color by $11, although we saw a pair for a buck less three weeks ago. They keep beverages hot for up to four hours or cold for up to twelve hours. Each mug features double-wall vacuum-insulated stainless steel construction, an autoseal lid with button lock, and fits most cup holders.
