We had a cute character one my daughter's first year at pre-school that was from J.C.Penney...very reasonable price (under $20).
Then, for the past two years, she's used the same one that we bought from MyNapPak.com. They are higher priced, but still not as high as some of the "boutique ones" and yet they are just as cute! We actually bought ours from a local retailer, but I cannot remember who...it may have been Learning Express. And, we bought it when it was 20% off. So, we got on sale and didn't pay for shipping. They are very cute and the website says "The all-in-one pillow, comforter and attached fleece blanket just for kids who take naps."
You can go on the website and click on RETAIL LOCATIONS to find a store that carries their brand close to you. They don't have many designs offered online right now. Here's the ones in Plano, Texas:
