I'll be comparing McDonald's flagship burger "The Big Mac" to Hungry Jacks's "The Whopper."
My local Big Mac costs $4.75 while the HJ's whopper would cost $5.95 for two burgers with the following coupon http://files.ozbargain.com.au/upload/110465/19136/scn_0001.p…. Some may argue that both burgers are near cost without the help of coupons, HJ's sends out their coupons by letter very often and many times you can find these coupons on the front counter.
For the cost of a small big mac meal, that will set me back a bit more than $8 dollars, I could go into to a cafe to buy a gourmet burger bundled with salad and a drink for only 2 dollars more.
It obviously depends on the city, because you would NEVER find a gourmet burger bundled with a salad and a drink for anywhere near $10 in Perth!
