OK, I had an issue and could not find an answer on getShopped.org. I finally did figure it out after much frustration...
De-activate the gold cart Plugin then go to "store Upgrades" and click "Reset API Key"
I still have been unable to find a contact email for GetShopped or a phone number - Very unprofessional!
I also attempted to sign in thier blog and was never sent a password.
Poor service and I am a patient person and not a complainer!
