We got them a few years ago on the special for two regular pillows with two free travel pillows for something like $40.00. I love mine, my wife likes hers but prefers a different pillow altogether, and I love the little travel pillows. I actually use one for backpacking because the memory foam compresses down so much in a stuff compression sack.
And we have the “chunky” ones as well.
