I've recently moved from an apartment into graduate housing, and have an extra 4-tier chrome shelving unit, purchased from Home Depot. The assembly is remarkably easy, and it's portable, strong, and looks nice pretty much anywhere that you put it. I actually have three total, two of which I am keeping and loving, but I don't have room for the 3rd, and so I'm looking to sell it to a good home. Here is the equivalent unit on Amazon:

I bought it for a little over $70 at Home Depot, and so please offer a price that you think is reasonable. I am a Stanford student and can drive it to campus on a weekend, and it fits easily in a generic sedan.
