$400 voucher is being advertised but Westfield Chatswood is throwing in an extra $100 and making it $500. Today and tomorrow only I was told.
Mod: Note that the OP is associated with JB Hi-Fi and posted the deal for Westfield Chatswood only, however comments indicate that it's available Australia wide. Check with your local store. Deal updated.
I too would like to know…chatswood is far from me
