Down from $2 … A two pack of a pen with two colours …. Now only 50c.
So that works out to be …. 2.5c per ink. If you don't care about the colour you're using to write then this is an epic price.
Nb Kmart delivery fee is $10 so you probably want to go in person. Maybe call ahead to your nearest store to make sure they still have some.
There's currently lots of bargains in stationery :)
