Coles has the Garnier Good 7.0 Almond Creme Dark Blonde on sale for $8.50 this week, halved from its usual $17.00 shelf price, so you're saving $8.50 on the spot. It's a permanent, ammonia-free formula made from 90% natural-origin ingredients, enriched with shea butter, and rated for 100% grey coverage that lasts up to eight weeks. Woolies has it too at $9.00 (down from $18.00) if that's more convenient, but Coles is the sharper pick right now. At-home colour doesn't get much cheaper than this, and with this shade running warm golden tones it's one of those buys you can throw in the trolley without overthinking it.
