Amazingly, the PetCo near my house had ONE adult blizzard. It's colors were a little dark, which can mean stress, but I don't buy from pet stores anyway
Your best luck for healthy blizzard babies would be through reputable online breeders (you can check the BOI for reputable sellers) or at a reptile show.
Here's a link to some blizzard baby pictures, provided by GeckoHaven - http://www.geocities.com/geckohaven/blizzards.html
But my favorite baby blizzard picture is the one below by GeckosEtc, which shows a blizzard and a banana blizzard
