Styrofoam Rx boxes

So I searched the old threads, but was wondering if anyone has found a place to "donate" or recycle the styrofoam boxes that pulmozyme is shipped in. I have given away to friends and family, but we get 3 of these suckers a month and my garage in being over run by them! I hate to just throw them in the trash. Any suggestions besides building an igloo with them?
