Unfortunately this deal has expired and is no longer available.
Looks like new American Express Business Gold Rewards cardholders have access to a new sign up:
- Sign up for G Suite by Google Cloud and get Gmail, Docs, Drive, and Calendar for business. Earn dollar-for-dollar statement credits for purchases of G Suite on your Card during your first 3 months of Card Membership up to $1,500 total.
Obviously a great deal if you can make use of the credits, but I suspect that won’t apply to most readers. If you do use G Suite you can actually pre-pay as well so anybody that uses G Suite should be able to make use of the full $1,500 (even if it does take you forever to get through it).
