On the Fly bottle warmer and was thrilled when I found out today that if you fan them on Facebook and follow their blog, you will have the opportunity to get a free one! The coupon code will come up on the blog but in order to get this - you must be a fan on Facebook and a follower on their blog.
These have a retail value of $25 so this would be well worth becoming a fan. I love mine - when I pump it keeps Gabriel's bottle warm for 8 hours!
