I purchased two mattress sets in November for $1534 and some change. I made the purchase with Mattress Firm due to their 90 day same as cash promotion. Yesterday, less than 30 days after the purchase, I received an email stating my pay off balance is $2789.95. They are no longer accepting 90 days same as cash promotion even though it was advertised at the time of purchase. Very disappointment in their false advertisement.
