Cheapest I've been able to get the Garmin Fenix 5.
Rebel sport 20% off sale, including new Garmin Fenix 5,5S,5X
I price matched a Fenix 5 at Harvey Norman for $639.20 and then used Amex offer (spend $350 and get $50 back) to make it $589.20!
I'll edit post when I get home but since the rebel sale is only one day I wanted to let others know! Beats the recent eBay deal which has you waiting for 5+ weeks!
I can submit my receipt if others require!
