On line pet product store
Go to "tags" on the left side menu.
They have one for "free," just pay $1 for shipping and handling. For their new customers, only (if you ever orderd from them, you may be out of luck.)
Even their other tags are $1.00 plus a $1.00 shipping and handling fee.
Haven't had time to check out their other pet items, just thought I'd pass this along!
