50% off @ Big W & Coles this week
not as cheap as Amazon, but many products are OOS @ Amazon anyway or without prime membership
Some products are cheaper @ BigW, some @ Coles and some @ Amazon
For some products they don't stock the same size, better to compare the unit price carefully
Another option is Chemist Warehouse, ask them to price beat the difference by 10% (not 10% off the price)
if you shop at BigW, don't forget to purchase 5% off eGC ahead, available from multiple platforms
Happy Mother's day!
