I went to the store to buy this one shelving unit for my material and stuff that lined the floor (what a mess, I was tired of it). I thought the cost of this unit was $98.00, I got there and it was $149.00...sheweeeeee. Well...I wasn't going to get that, too much money. Instead, I found these metal cubes that attach to each other and they were about 1/4 the price of the metal shelving unit. I feel so good to get all that stuff off the floor and to have somewhere to put my projects that I am working on. It is great.
