CoFlex prices may depend on size. For horses I see a lot of 4” wraps and they are more expensive. I paid ~$12 for a 6 pack of 2” x 5 yd coflex (is that too much?). Buying one roll at a time will be pricey; buy in bulk and make sure you are buying the width you need. $.02

Edit: that was too high. https://www.amazon.com/Ever-Ready-Adhesive-Cohesive-Approved/dp/B00IQTQU6K/ref=sr_1_fkmr0_1_a_it shows it at ~$1 per roll for 12 rolls.
