Where to find cheap/good kids toy storage?

It would depend on the size of toys. You can check out craigslist and look for a bookshelf type piece that suits your height/length and stack the toys that way. You can also post "wanted" ads on craigslist free. Check out your local Goodwill or Salvation army or second hand store. It is also fairly easy to build a sort of shelf and easy too. You can search online by typing "how to build a shelf" and you can find step by step instructions as well as a list of what you will need. Then you can have the kids paint the shelf and make it their own. If the toys are smaller, Dollar Tree has tons of Sterlite tupperware type stuff. They are advertised as shoe "boxes", but we use them to store in small pieces and barbie dolls etc. They are clear with either a blue or white lid. We have a ton of them in our house, I use them as a makeup "bag" in the bathroom. They are also great for traveling. Good Luck! I know toys DO pile up, you should see our house!
