I'm using more clay so I decided to bite the bullet and buy 1,000 pounds once instead of two orders 6 months apart of 500 so that I could get the discount. I wasn't prepared for how many boxes 1,000 pounds is. We brought it all inside so it wasn't sitting in the driveway, but I'm taking it down to the basement in 1 box increments when I'm going downstairs. It's going to take a while.
