Just like tv and movies, department stores have a target audience (or target buyers in this case). And for Target and Big W and Kmart and David Jones and Myer ( sorry for all the 'ands') the target is mothers. I'm not surprised. But I can always buy from better places. Brick and mortar stores are losing the battle with online retail and if they have to institute these kinds of policies, so be it.
And i'm rambling.
