I used this code to get some pillows. The ComfortFit pillows are already 30% off so that helps as well. Just be sure the total cost after sale is over $100. You can also just use the discount to help with pillows not on sale, and over $100. It can bring down the pillows to a more reasonable price.
I have used both tempur pedic and sleep number pillows and have enjoyed both. It is helpful to go to a store to try out which line you want to focus on if course. I missed out on the 50% off TP pillows deal recently and was happy to get a similar deal on these pillows.
