Apparently this is a vanilla chai tea latte from another company, but I'm going to be talking about the one from Mocafe. I am SO addicted to it. I don't order offline, but I do get it from Marshall's for $4 a giant can. It tastes absolutely delicious, and I get around 6 or so cups a can for $4, which is much better than Starbucks. Even better, it's apparently made from natural ingredients so I won't feel as guilty about it as I would at Starbucks. xD It's from powder - just add hot water and you have a delicious drink.
You can order it offline in bundles of cans here, or from Amazon.
