IGA has the Bref Escapes Hawaii Rim Block Toilet Cleaner (50g) on special at $3.50, saving you $3.50 off the regular $7.00 shelf price, that's half price for something most households go through every few weeks. Woolies is actually the cheapest this week at $3.00, so if you've got both nearby, that's your pick. Coles is also running it at $3.50 (down from $7.00 too), so IGA and Coles are matched on the deal. These little rim blocks are the kind of thing you throw in the trolley without thinking, worth stocking up on a couple when they're this low.
