The mere fact that you can purchase "my pillow" at Walmart for $52 or from the TV ad for 'only' $99 plus they will send you a second pillow 'free' plus shipping and handling would indicate strongly that the TV offer is false. There were apparently BBB complaints in addition that there were costs to return the pillow within the 90 day 'refund' window beyond mere shipping costs.
The other night I saw an infomercial for Copper Chef pans. They were 4 payments of $24.99 and they would lop off one of the payments so you were only paying about $75 for the pan. A quick google showed the pan deal for $60 at Walmart or with additional tools for $59 at Walmart. A check of some reviews of the pan were uniformly negative by anyone who had used the pan more than once or twice--the interior coating was flaking off, the pan warped easily, the lid was flimsy, etc. The comments about attempting to return the pan were also very telling as their 'customer service' was outsourced to a non-English speaking crew who seemed to be deliberately not understanding 'return for refund'.
If you believe you are getting good deals from infomercials you need to do some research before you jump.
