Aldi has Di-San Laundry Sanitiser 2L on the shelf for $6.99 right now, and if you've been grabbing it at Woolies for $4.00 or Coles for $4.50, those are actually the better picks this week. IGA has it on special at $13.00 (down from $24.00, so a $11.00 saving there if IGA's your only option), but Woolies still wins outright on price. Di-San kills 99.9% of odour-causing bacteria in both front and top loaders, so it's a solid grab if the kids' sport gear is piling up or the towels have gone a bit funky. Chuck it in the trolley alongside your regular detergent and you're sorted.
