I've done basically a gut renovation of my house over the last year, and the East Liberty Home Depot has made this process ten times more bearable. Most of the staff can give you reasonably good advice about which items or tools you should purchase, they all have a good understanding of where things are in the store, and the return policy is amazing. When you make 3-4 trips per day back to the store, after realizing that the simple wiring of a light that you planned has evolved into an afternoon installation project, having someone who is nice about you returning parts and asking a million questions is such a stress reliever. If you need to use the bathroom when your plumbing at home explodes, you may get one or two odd looks if you bring a toothbrush, but even then the staff seems to have seen everything and maintains their nice and calm demeanor.
The only reason I wouldn't give it 5 stars is because I was once (out of 50 times) given very bad advice about which stain to use that basically ruined a brand new $1000 wood door, and the appliances tend to be overpriced by comparison to Best Buy and Sears.
