My guess is one use. You're also suppose to use it with the email account that you opened the registry with. DH is going to finally buy the travel system I want today with the 20% off.
Pretty sure it's a one time only code. I used mine last night to get the infant seat and extra base we wanted. Saved us a ton! It was like we got the extra base for free!
Re: Target 20% for Registry Troubles - 1x use only?
