Affiliate Marketing Secrets

I just got a letter in the mail from chase that offers me a $150 bonus when I open an account with them. I currently do not have an account with chase but was planing on opening one. I feel though as if there is something sneaky with this such as I get this money deposited and then get charged it all back for keeping the account open.
Heres what it says
