Plastic Rack Question

[reptidude1]

I was looking at the Heavy Duty Shelving Units at home depot. I think it's cost around $40 or $50 bucks. All you have to do is cut the poles the size of the tubs. I used a $15 shelf for my baby rack and haven't had any problems. Here's Video so you can see what i'm talking about. I'm not going to use the board he used. But that's up to you

I actually did exactly that before i made my melamine racks lol , but i think im going to just go with the xPVC method to make the racks that im looking for.
