Okay, I have a number for you. I recently received 40 yards of fabric in a large Express mail box, which measures 12x12x5.5". That box was full, and the ebay seller claims she can pack up to 40 (no more) yards in a box.
I converted those inches (12x12x5.5=792) and found that it is equivalent to 11.7856 dry quarts. Your 58-quart container is 4.9212 times as large as the postal box, so if you filled it absolutely full you would get about 196.85 yards in it (4.9212 * 40).
So... 8 containers *196.85 yards/container = 1574.8 yards! At $12/yard = $18,897.60. Sounds like a nice shopping trip, yes?
