Hello, after joining and reading as much as I could possibly read, I've decided to buy a cup! Around here, the closest thing I could find in stores was Insteads [I checked at Target, Walmart and Kmart. Target and Walmart stocked 4 boxes, placed either on the highest shelf or on the very bottom. I couldn't even find them at Kmart.] Insteads are cool, but I want something more.. permanent?
