How's that? If you're filling the floor 1' high that's 1x10x10 or 100 cubic ft at $90, for double Amazon's price. Parity is 2' high. When I had a storage unit I think I was using about 30% of its capacity, which is cheaper than Amazon but also less convenient. Seems like a reasonable tradeoff.
Apologies; That's only for long-term storage, where the $.90/month per cubic foot is significantly less than the $4.24 ($22.5/half-year, ~$.49 per month) that Amazon charges past the first year.
