I went to do the shopping today at Coles Merrylands and was told at the register that because I spent over $100, I was entitled to 10% off my total bill.
The checkout lady told me it was running until September, sorry don't have an exact date and it looks like it's only at the Merrylands store.
See receipt for the 10% discount.
As per comments it looks like it's to draw people in to the new Stockland mall so will be Merrylands only.
Anyone know if this only applies to Merrylands?
