First post so be gentle…
Went to Coles and noticed they had a half-price sale on Mirabella lightbulbs. No price was on the Genios so thought I'd give them a shot, and they scanned through at $1 each.
This was at Prahran Coles, could be elsewhere as well. I bought the last 3 e27 bulbs.
Edit: there were some b22 left, and plenty of other bulbs on sale at 50% off ranging from downlights, to LED bulbs. All located at the light section.
Edit #2: looks to be VIC wide, was spotted in Malvern as well as per comments
Receipt uploaded as proof. Good luck!
