Harvey Norman has three active promo codes which are valid on all items in their Health and Fitness category. There are a few items in there on sale already, so you could stack the code with these offers to maximise your savings.
Here are some examples on fitness trackers with each of the codes:
* $15 off $100 min spend - Jawbone UP2 Wristband for $100 vs. $115 at Officeworks, $149 at Telstra and $179 at JB Hi-Fi.
* $25 off $150 min spend - Jawbone UP3 Wristband for $143. Although COTD has the next best price at $149, you'll find this fitness tracker for $168 at Officeworks, $198 at Joyce Mayne and $279 (?) at JB Hi-Fi.
* $30 off $200 min spend - Microsoft Band 2 for $259 vs. $277 and $289 elsewhere. Earth has posted a deal on this wristband back in June, when it was selling for $249.99 at Microsoft AU - I think this was the best price I have ever seen this go for.
These Harvey Norman promo codes are valid until the 23rd of July on all items in the fitness and health category as long as you meet the minimum spend requirements.
