Amazon is now offering the Ember Smart Tumbler for $138 shipped. Regularly $179 directly from Ember and at Best Buy, this is nearly 25% off the going rate and the lowest price we can find. While we have seen this one down in the $120 range once previous to today at Amazon, today’s deal is otherwise the lowest price we have tracked since the brand’s tumbler form-factor landed on Amazon last summer. While this isn’t the Travel Mug 2+ model that sports Apple Find My tech – that one regularly fetches $199 and is now on sale for $175 at Amazon, it is a sort of more rugged and heavy-duty design with the integrated handle.
