Get this Bubba Envy S Vacuum Insulated Stainless Steel Tumbler (24 oz) for $7.19 right now (reg. $15.99). This is by far the lowest price so far.

I have one of these and it really works well–especially for the price! In fact, I’m drinking out of it right now. I try to fill it up three to four times per day to get enough water.
