You can now open both the AMEX Business Platinum Card and Business Checking at the same time to earn a 150,000 + 30,000 welcome bonus. If you open both, you can also get an extra 20,000. So if both are successfully opened, that’s a total welcome bonus of 200,000. This appears to be a public offer. If you want to get it, it’s best to apply for the two accounts separately through the promotional link below.
