One Kings Lane is offering a $15 credit when you sign up today. They offer lots of home décor and gift items. There are some things priced $19 + $4.95 shipping right now but nothing that would be FREE. But your credit is good through 4/14/12, so you will have plenty of time to find something for FREE or very cheap with your credit.
Last time they had this credit, I signed up and waited until they had a Melissa & Doug sale and got a really great present for my niece. I ended up paying $1.95 shipped! :)
So sign up today, hold on to that credit, and I will let you know when I see a good sale!
