I live in a tiny 2 bedroom apartment with my wife and child. 1025 square feet fills up fast! I am looking for some stackable water storage containers that I could put into a closet and keep out of sight from the maintenance men. 5 gallon containers would be nice. I looked on Amazon a bit, but the containers seemed a bit pricey at $20/piece. Hoping to store 50 gallons for <$100. What do you all use? Bonus points if you live in an apartment and share experience.
