I order from http://www.cafebreville.ca/ all the time. Aside from great customer service, shipping is FREE!!!
Even though they sell the US box sizes, it still works our much cheaper than ordering via Timothy's.
Timothys charges $15.75 for a box of 24 K-cups, which works out to 65.6 cents/K-cup. Cafe Breville charges $11.99 for 18, which is 66.6 cents/K-cup, so I don't see how Cafe Breville is "much cheaper" - looks to me like they're about the same.
