Play it again sports -treadmill

Trying to sell a lightly used treadmill. Going to post it on Nextdoor, marketplace, etc. just curious if anyone has sold a treadmill to Play It Again Sports and what they got for it.

Selling a flex deck t5 - looks like it’s discontinued now. I got it for free from my work but it was a few grand! I used it a few times and tried to get the pup into it but no go. Would be cool to get $400-500 but I doubt I’ll find that on Nextdoor. Any other business suggestions to sell to are appreciated!
