Less of sale, and more an improved price due to the falling pound I think, but still one of the best historical prices for this smart bulb twin pack. Singles are currently going for $49.95 at Bunnings. These are not the full colour (i.e. purple, etc.) version, but changeable through a white-yellow spectrum.
[edit 27/10] Annoyingly for me, but maybe happily for others, after pulling the trigger at higher price points, it's now fallen even further to $46.85 per pack :/
