Appears to be four tiers of eight bins each plus one six bin level at the bottom for a total of only 38 bins. For the $750 to $800 asking price, that's an awfully high price to pay for storing only 38 items unless you need these huge bins for your work or hobby that uses a large volume of nuts, bolts or whatever. These rotating bins are normally seen in older hardware stores where the bins are filled with nails or screws etc so the customer can easily see what he wants and pick a handful, and buy them by weight. Very limited use for a personal garage unless you had a specific need. IMO, will be hard to sell at those prices. But give it a shot since there may be somebody out there who would pay anything for it because he actually has a need for it. Also, it's a hoarder's dream because he can fill it with all sorts of **** he can't stop buying.
