If anyone is keen on Mumm, Myer seem to have a decent offer currently. A triple pack of individually packaged "Mumm Cordon Rouge Champagne, dressed to
impress in an elegant Patrick Jouin dinner jacket." for $120+delivery. But they offer 2000 Myer one credits which equates to a $20 voucher. Makes the bottles $33 each plus whatever delivery is.
I'm not a fan so I haven't explorer farther.
