I just cant push the button on more WOW, given what has happened in the UK to the once unassailable positions of Tesco and Sainsburys at the hands of Aldi and Lidl and the like, I think WOW and WES might be in for significantly tougher times in the next decade. Aldi has doubled its market share in Oz the last 5 years to 10%. WOW may be a value trap at this price.
My 2 cents only of course
You might be right Erko...but what I have been doing over past several years is
1) Buy veggies and fruits from farmers market. Way cheaper than all supermarkets.
2) For everything else I find 80% of the time when buying stuff from Woolies I tend to buy products (eg. bread/juice/cheese etc.) which are on specials (20-30% off) along with their homebrand products (sugar/salt/ketchup etc.). My grocery bills hardly exceed my allocated budget.
3) And for products that I am particular about (Nutella, Connoisseur ice cream, Nutri-Grain Cereals etc) I always walk through the isle and buy heaps whenever they are on specials
I have been to Aldi several times but have been frustrated with lack of certain products not available and those that are available lack variety and are usually similarly or higher priced than same products from Woolies which are on special.
So as long as you are flexible Woolies can be cheaper option. Same goes for Coles I guess if you buy stuff from there.
My own experience has been Aldi is not always cheaper. Haven't been to Costco so cannot confirm if it is any cheaper.
