A new promotion is here. New Amazon Business accounts can now activate an offer and get 40% off through June 30, up to $150 off. After you finish registering, you can see the 40% discount in your account overview. In fact, anyone can activate it—just choose the free Duo account. If you register multiple accounts to take advantage of signup bonuses, try to complete your purchase as quickly as possible, because Amazon may eventually notice and close the extra accounts, leaving only the personal account.
First, go to your account and look for this offer
Then enter and register
The Duo account is free. Sole proprietors can sign up as well (use your SSN instead of the EIN when filling out the form)
