storing transformers that we cant fit in rooms

i have in the past years found that file storage boxes that you can either get from friends or buy at staples or office depot works the best. they are stackable and easy to carry then totes. unfortunately if your keeping them packaged then it may take alot of boxes, but if they are out and free then do what ive done---transform them to a compact state--you can store alot that way in boxes.

 

What he said. Staples sells 10 "Economy" boxes for ~$11. I've recently reboxed most of my collection to try and save some space. That being said, I fully understand your space problem, as I'm running out of space myself!
