How much would you pay for a used Gaming Chair?

We bought this really nice Gaming Chair for $150 a year ago and we are wanting to sell it at a yard sale this weekend. We want to get as much out of it as possible, but I know that people are looking for a good bargain when they shop at a yard sale. How much would you buy one for? It has hardly ever been used and is in perfect condition…

In general, anything used (even hardly) is automatically half price.
