Steps to get your $50:
1. Go to ING Direct Canada and click on the Sign Me Up tab
2. Choose the account you want to open (savings account, chequing account, RSP, TFSA,etc.)
3. Complete the form.
4. Input 35561445S1 for the orange key field
5. Mail a cheque from your current bank account to yourself in the amount of $100
6. Ensure you write down your client # on the memo line of your cheque
7. Mail the cheque to ING.
Once ING receives your cheque, they will automatically link your new ING account to your current bank account, and deposit the $100 funds as well as the $50 bonus! You'll then get your own orange key to start referring others to get more bonuses! Great deal, eh?
