With the house finally done and the move-in complete, I've shifted gears to implementing our prepping plans. I have a dedicated area of the basement (shared with mechanical equipment) that also goes under the stairs for storage of preps. I know buckets are the storage system of choice for most, but while packing empty buckets in to see how many I can store I can't help but see all the wasted space between them. Has anyone come up with a solution or found a square or rectangle storage system that seals as well as buckets? It's not a real big deal, but I'd really prefer to store everything as tightly as possible. I've looked at rubbermaid tubs at the store but haven't found anything even close to what I want- namely a sealing lid.
