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 
Is this for sale? I’m interested in buying it!!
None of these mugs are for sale but you can go to the FB page and see if any collector has a spare one to sale or trade with you. Thanks.
