Maybe I’m missing something but are these sold as a pair or are they $17.99 each?
It’s a pair–2 straps.
Only 200 lbs each?
These just arrived the other day and they are awesome at 1000 lbs each! And they cost less and come with locking Carabiners.

These are 12’ long. While there are a lot of other options on amazon slightly cheaper and/or w/ carabiners and loops for adjusting, what you linked is just too short for a lot of trees.
