I'm not sure how long they will be discounted for.
Looks like a good price. I have a different model Garmin HR watch that I wear when I run. It is awesome for keeping track of how far I've run and how much fitter I am becoming. I've even noticed my resting heart rate starting to decrease as my run times come down. I had a quick look online and I cant see it much cheaper even from OS.
