If you are looking to more than double your money risk free, here is a way to do it. Chase is offering a special deal on its checking accounts, where Chase will pay you $125 if you open a new account with $100, and set up direct deposit.
The catches are that you can't be a current Chase checking account customer nor have an account that you closed with them in the last 90 days. There are also some time limits on the setup. Also, there may be a monthly fee if your direct deposit is less than $500 or you can't meet any of the other requirements.
The deadline for this offer is January 11, 2014.
