If you shop at Sams you can get their Domino sugar boxes (2 lb bags of 10 x sugar and brown sugar are shipped in) and use them for storage. They are good boxes and have lids. These fit perfectly under our beds. I also use them to store empty caning jars in the shed. Because they are uniform in size they stack nicely!
Every trip to Sams we get a couple boxes (and lids) even if we are not buying the sugar! )
