If you've been following along for the last few weeks, I've been reporting on my experiences with the Progressive Snapshot device and discount. I've already gotten my initial discount and am now still running both devices to determine my renewal discount.
If you recall, the initial discount was 7% for me and 13% for Jen - which saved us about $15/mo (or $174 per year). After another 2-3 weeks our discounts are both going up! Jen is up to 16% discount and I'm up to double digits at 10%. At that rate, we would save about $20/mo (or about $230 per year) over the original rate! That is, unless my math is wrong... which it might be.
We'll obviously find out more when my renewal comes due again - which should be around the first of August.
