Got this in my email this morning - Rebel has a 20% off flash sale that's on tonight only. Looks like there was early access for Click Frenzy.
The Garmin Blue Bundle looks good that comes with two HRM straps. You could probably sell one/both if you don't have a need for it.
Some more deals here I'm looking through: https://www.rebelsport.com.au/afterdark?src=earlyaccess&lid=…
Must click through the Early Access deal page to activate discount.
I will not buy it even with 5 heart rate monitors. It is two and a half generations old!
