I haven't bought anything from Myer, so I can't get this $10 voucher.
At least I can get $10 welcome voucher and $10 birthday voucher from David Jones ;-) Not bad for free chocolate worth less than $10 :P
Anyone can register for David Jones as new member and get that $10 welcome voucher and $10 birthday voucher without spending :)
