I used my credit to purchase a book that is said to help improve self esteem (you can choose one for your child or for couples) you write down something that you "like" every day.
Following is a link if you are interested.

I use the everywhere button to find the most deals :)
Another nice thing about plum district is that if 3 people purchase the item, you get it for free - so anything you purchase, you should recommend it.
