A.P.
I have seen them at Walmart along with the lower case letters. Try Shopko and I have seen them at Target. I love them too and so do both of my children, 3 1/2 and 20 months. We also have the Fridge Phonics Barn that you have to match the animals together ( the front and the back of the animnal). They love that one too. Good luck finding them though they are hard to come by, they come in and they are gone off the shelves right away.
