Aside from rude employees, Lowes is highly over priced. Many times I have found the same thing for much less.
Just today I bought metal shelf brackets at a competitor one mile down the street for much less than Lowes. There may be something that you will need at Lowes that you can't get any place else, but it's rare. There are lots of other stores that will have the same item for a lot less. Also other stores are offering the same guarantee policy that Lowes offers.
So to review, think twice before you spend more than you have to at Lowes. Always use discretion.
Reason of review: Pricing issue.
Lowes Cons: Way over priced.
