What’s a good buy price for a slack line?

[BDKmom]

I, of course, just missed the lightning deal on this earlier today. It was one of those things that I didn’t know I wanted until I saw it on sale, and realized it would make a great gift for DS. Then, literally by the time I could walk out to my backyard to make sure we had two trees it could work on and walk back inside, the deal had ended.

This is the one I am looking at: https://www.amazon.com/flybold-Slack...4uL&ref=plSrch

Right now it’s around $58. I can’t get it to pull up on camelcamelcamel, so I can’t tell what it usually goes for. How much did/would you pay for this?
