Visit a branch, and check in using Facebook Places during branch hours on your compatible smartphone. Press 'Check in to claim'.
Present this screen within 3 hours to the branch staff before opening a new Everyday Account. Deals can only be redeemed during branch hours.
Finally, simply make a purchase with your new Debit MasterCard® or Keycard either overseas, online or in store within 30 days.
You can then enjoy an Events cinema double movie voucher every month for 12 months, provided you keep your account active for the entire period. This great deal is valued at over $430. But be quick as it’s only available to the first 2,200 people who claim this deal in branch and open an account while there before 15 September 2011.
DISCLOSURE I am a CBA employee but I am not posting here in an official (company representative) capacity.
Not available for existing customer I reckon?
