Look for an email with the code
Only the anniversary version comes with the car packs and extra credits in the form of a leaflet inside the box. If you pre ordered you would have gotten another code for an extra 5 car pack in your email.
It should already be there.When?
When?
I got it the day before release.
My code email was sent out the same day as Amazon's package tracking email. Amazon's system is solid as a bank vault.When?
