Doing the weekly grocery shop can be a very expensive activity.
However, we may have just discovered a hack that could see you save 50 per cent on your shop.
Yes, 50 per cent!
Simply go to the 'specials' section of the website - we've used Woolworths as an example below - and select 'half price'.
You can also filter your results to show you savings across categories such as 'meat, seafood & deli', 'bakery', 'freezer' and 'household'.
Coles also have a similar savings system, which you can access by selecting 'catalogues and specials' in the top menu bar.
At the time of writing, the 'fresh specials' of the week are fruit and veg.
