If you're in the market for a workbench/storage unit from HD, check up near the front where they usually have all the seasonal stuff: Halloween and Christmas decor, AC's, etc. If they received a bunch of workbench or storage units recently, they'll have about 6 or more assembled for you to look at.
If you look closely, you'll find at least a couple with a ding, scratch or bend where it doesn't belong. Talk to a manager and offer to buy one that's damaged, but not where it's obvious -- like on the rear or underneath the unit.
I managed to get a nice discount off the already lowered sale price for a rolling workbench with drawers similar to one I already have -- only the new one was deeper front to back.
The sale price was $299.99 + tax, marked down from $399.99. I got it for another $50 off IIRC.
