Inspired by this post:
http://www.mrmoneymustache.com/2012/01/23/gaming-the-system-with-rewards-credit-cards/ I decided to take advantage of the next offer that came my way.
Chase owns the mortgage on my duplex. They always stuff offers into the payment slips that come every month. This month's was $150 to open a checking account. The only restrictions were that I had to keep $1,500 in the account and not close it for 6 months.
Easy Money! I opened the account Saturday. A 21% annual return!
I'm sure some of you mustacians have found even better deals than this. Let's post them here!
