Happy Days & Nights Diapers?

I have a coupon in the mail for the new Fisher Price Happy Days & Nights Diapers. Sounds like a good business for a box of "day and night" diapers. Has anyone tried it? Is it good? I know that is sold exclusively at Toys R Us where I am. I were a good business too. I really like the idea economic package for the day and night. I would save money.

I think its really a great idea. VERY cheap (I live in California and are $ 7 a pack of 56. I have not used, but I'm thinking of getting a package from my next trip to Babies R Ust
