expired Philips Hue E27 White Bulb $19.89 @ Bunnings ($18.89 @ OW Price Beat)
Philips Hue's white entry level bulbs for smart lighting is a fairly good price at Bunnings - cheapest I've seen them at. Bunnings had these at $28 a couple of days ago, I purchased 10 and got them to price beat Amazon's price of $19.99 (scored them for $17.99) but it looks like they have updated their pricing to reflect Amazon.com.au. Don't forget you can get OW to price beat Bunnings for a further 5% off the $19.89 ($18.89).
I also picked up the Philips Hue White Starter Kit (Bridge & Two white bulbs) from Bunnings and had them price beat Amazon.com.au (getting it down to $85.49) - this price beat is still available.
