I was just looking at Yoga props and came across this AMAZING deal with Marg's business, Yoga Mart. I do not have the bolster but have used them when I taught at the Yoga Center of Lawrence. The bolster will smash down a little bit with use, which is actually very nice.
I am not receiving anything (monetary or otherwise) for posting this link, I just like to support small businesses AND this is an amazing deal. The link below should take you to that page.
