Since forever LOL!
Every supermarket has them. HAHA, that really is sad!
Do you have online grocery service your area? Get on the Coles or Woolies website (reccomend Woolies the online service is available in more places).
You can do an order (any amount) have it the next day and delivery is $12! If you want you could order $100 worth of poptarts and have it delivered for $12.
Seriously, think about it? Who would bother with driving to the store, pushing around a trolley and loading it with goods, unloading it at the register, loading it back into the trolley, unloading into the car, driving home, and then unloading and putting away, when someone can bring it to your doorstep... for TWELVE BUCKS?!?!
You can shop at home, in your PJs's at 3am. It's an absolute bargain, and it's revolutionised my life!
