Misleading Ninja Cremi coupon

I got a Ninja Cremi. I wasn’t planning on registering the product until I saw this coupon. I thought it was for two free pint cups for the appliance. It was not, it was for a 10% off promo code.

I thought this was unusually ambiguous for an organization like Ninja who makes decent appliances. I complained via Twitter, they said that they would pass my comment along.

The question I have is, is it misleading or not?

It does not look like a 10% off coupon; it looks like they are offering the container if you register.

They are offering you 10% off a purchase of extra storage cups? Yes, I would find that misleading.
