Dexcom Stelo Details
2-week supply $55 (1 biosensor, no commitment). 1-month supply $99 one-time (2 biosensors). 1-month subscription $89 for 2 biosensors, but shipped every 27 days - about 13.5 cycles a year, so roughly $1,201/yr rather than 12 x $89. The cheapest true annual path is the 3-month subscription at $252 (list $297) for 6 biosensors every 87 days, about $1,057/yr, which Dexcom markets as 'starting at just $84/month'. All options now include 1:1 video calls with a dietitian. 15-day wear, OTC, no prescription.
FreeStyle Libre 3 Details
Retail cash price around $241/mo for two 15-day sensors. Abbott savings programs and pharmacy discount cards can bring this substantially lower. The OTC Lingo sensor is built on this same platform.
