Finish Quantum Dishwasher Tablets 60 for $15 Kmart
(25c each for the mathematically challenged)
In the new catalogue.
Also, a video projector and screen for $249 if you are desperate ( "supports HD1080p" ), some really ugly headphones for $179 (you must be kidding k-mart), …
nothing much really. Except maybe someone can make a listing for the big list of aged-care items in there.
that's cheap.
