This should probably be
if UserCheckout.objects.filter(email=email).exists():
Do not use count() for checking whether or not a record exists. You are
also checking against User objects, and not against UserCheckout objects,
which doesn't make any sense based on the code you've posted.

Here is where the actual error is coming from. Your validation only checks
User for a unique email constraint, but then you create a UserCheckout
object without first checking the unique email constraint for UserCheckout.

You'll only get this error if a user checks out using an email address that
matches an existing user, not an existing email that's been used to check
out before.
Is the intention to create both UserCheckout and User objects (which can
log in) through this process?
