I've been in the market for a Purple king-sized mattress for months now and have been looking for any kind of discount to no avail. It seems Purple finally developed a pillow and have a Kickstarter campaign going until October 22nd that has the following options which include free shipping within the US and are tax-free:
$79 = 1 Purple pillow
$149 = 2 Purple pillows
$699 = 1 Twin XL mattress + 2 Purple pillows
$999 = 1 Queen mattress + 2 Purple pillows
$1299 = 1 King mattress + 2 Purple pillows
The pillows will cost $109 each after the Kickstarter campaign ends. If you were looking to buy a mattress anyway, you are basically getting two free pillows. At the time of this post, the campaign has raised $1,150,933. If they hit $2,000,000 by the deadline, then they will also include pillowcases for everyone.
The main selling point for me was the fact that Purple's product design distributes heat so that you don't have to deal with heat retention like you would on traditional memory foam.
