I've joined forces with the hobbyDB team to create a database of every Starbucks Mug ever made! You can use hobbyDB to manage your collection and wish list, show it off, find values for your mugs, and to trade, buy and sell. We currently have four volunteers and would love to have more join the team. If you'd like to help, contact the guys at hobbyDB.
Starbucks City Mugs 
I was really hoping the ‘you are here’ collection was worldwide- my boys brought us home a couple from America and I thought I could start a collection when we visit cities in the UK and also on our trip to Australia. Love the size and fact that they stack. Any chance of a universal range?
