Joann Fabrics is having a 70th anniversary sale on their web site, and a lot of their craft storage bins are 50% off if you buy them online. This includes some of the larger shelving systems like Sterilite, smaller compartments, partitionable boxes, etc. The sale lasts until this Saturday (Aug 17).
I've seen people say that they use Sterilite and such for storing their lego, so maybe this will be of use to someone. Especially since I know you manly-men AFOLers might not browse fabric/craft store catalogues quite as often. *cough*
