This is the worst business I have ever encountered. I ordered two 3-tiered shelving units for almost $200 including an absurd $53 shipping for UPS ground and I ended up getting two shelves that attach to nothing. The picture mislead me to believe it was a 3-tiered shelving unit taller than a man and it was two small shelves with nothing to support them. Absolutely useless. When I tried to return it they wanted to charge me another $53 to ship it back. So in total a $106 waste of money for literally nothing at all.
