Yes, DealFetch.com.au is yet another group deal aggregation site, but at least it has a potentially worthwhile twist. The site add location details to deals and lets you pick ones near your suburb, so you can filter out cheap restaurant meals that require you to drive for kilometres in peak hour traffic.
The site currently covers Sydney, Melbourne, Brisbane, Perth and Adelaide, and collects deals from Cudo, Ouffer, Livingsocial, Scoopon, Spreets and Stardeals, amongst others. You can browse deals for each city, or sign up for a daily email. A quick browse around Sydney deals suggests that the outer suburbs aren't exactly drowning in offers, but your experience might differ.
