If I were you I would either:
1) Keep the receipt and exchange it when new stock comes in (or if you find it at another branch of the same store chain)
2) Get a refund and buy it from another store. BHs are available at Myer, Kmart and I think some people have sighted it at Target (it'll probably be more available there after their sale![]()
). Eventually all the major chains will get it... so yeah, I'd be tempted to refund it and just wait to find another one later on.
