The BBB revoked its accreditation of My Pillow for violating its advertising code.
The bureau said the company's buy-one-get-one-free offer could be mistaken as an everyday price. But it should only be available for a limited time.
The BBB also said images on the My Pillow box do not match the product inside. My Pillow is also accused of offering a full warranty when it wasn't full.
The company said it will make changes this year.
