We’ve been fans of Ember’s temperature-controlled mugs for years, though given the price tag, we admit that they’re somewhat of a luxury purchase. Thankfully, if you’ve been looking for a more affordable option, Woot is selling the Ember Cup in black for $32.99 ($67 off) with a 90-day warranty through November 7th. You can potentially save even more as part of Woot’s larger Home and Kitchen Sale, which lets you save an additional $20 off orders of $100 or more when you use code COOK at checkout.
