Each shop has a different way of doing things.
Sometimes the best bargains can be found on the store's website, or at least there is a better selection online.
I figured out at the end of the last soccer season that Rebel Sport's sale boots are often just as cheap as overseas stores and its online range is better than in my local store.
Rebel Sport group marketing manager Tanya Laurence says signing up for email updates is the best way to get early notice of sales.
Dropping in towards the end of the sales can be very useful indeed.
My teenage daughter stretches her budget by making a beeline for final clearance tables and rails.
At Farmers and other stores such as The Warehouse there are two types of sales: one is discount events for a specific timeframe; the other is clearance lines, where goods are discounted until they go.
These two retailers use dot labels on the clearance range and if you're lucky you'll get two for the price of one on already discounted goods.
