Instant Chai tea mix?

Looking for some really good instant Chai Tea mix in the lower mainland. I've been going down to Trader Joe's to get their spiced Chai powder, which I really like, but it's sort of expensive and a long way to go.

Any ideas for brands and locations to pick it up that are local? Doesn't need to be super-authentic, just tasty and easy to make without extra perishable ingredients - powdered milk with sugar and spices is totally fine, just want something I can keep in my desk drawer at work instead of feeding Starbucks.
