The best answer to this question is, it depends. If you have a collection that needs protection in a climate-controlled environment, then it's worth the price. If you're moving and don't have room in your new place, then it might be worth it. If you are willing to declutter, then you could donate or sell what you don't want to take with you. Storage isn't worth it if you have storage space where you are currently living, or if you're storing things that you don't need or want.
