There is something wrong with this item’s sale because of it being priced at $650. The normal cost of similar capability & quality carts ranges between less than $100 to $250, depending on the construction & quality.
This one is priced at $870 on Amazon - 700 pound capacity. Hard to believe, but it is rated at 700 pounds capacity + 4 shelves. Definitely at the apex of capability and cost. But if you can work with 3 shelves and less weight capacity or have different needs …
For instance, Luxor offers a 3-shelf, 400 pound capacity cart (in grey) for $115. They also offer several models in colorful options - the pretty blue cart is $136 and black is $105 online.
My preference is my stainless steel cart with a large lockable box at the top with two shelves below.
