Is it only me but I look at the promotion at Woolworths for purchasing cookware as poor value. You would have to spend $100 just to get $5 of a mug for $5 which I would not pay more than that without the stickers. The best "value" you can get is for a bowl at$15 which is meant to be worth $30.
I basically give this promotion a big miss.
Just wait for it to finish. Price is then dropped for clearance at about 70-80%.
