I just signed up for the Costco Pharmacy thing because I want to try the a Freestyle Libre 3plus without going through insurance.
Cash price for the Libre 3 plus is $73 per sensor at Costco. So if I had to pay out of pocket that would be the most reasonable price for me.
BTW they also sell a box of 100 Contour Next test strips for $20 but you need a prescription for that price for some random reason.
