Want to know more about BOGO?

This is an awesome explanation of BOGO coupons!  Even if you think you know all there is about a BOGO, read this anyway!  I'm sure you'll find something new to you.  There's even visual explanation.  Huge thank you to the ladies at KrazyCouponLady.com   80% of what I have learned from the internet has been from these ladies and the questions/answers from their blog fans.
