Given that similar tumblers cost about $12, that comes out to $18 for potentially 31 days worth of brewed coffee (or about 58 cents per coffee). I'm not sure if it can be used in conjunction with the Coffee Refill Tumbler, but one of the benefits of Starbucks Rewards membership is free refills on brewed coffee, so you might be able to milk the tumbler a fair bit if you have a mind to.
You can find the Coffee Refill Tumber in stores or online at the Starbucks Store while supplies last.
Starbucks offered a similar tumbler but for espresso-based drinks earlier on Black Friday.
