Lowe's went out of their way to rip me off on a SCREWDRIVER. Yup - a GD screwdriver (which was "lifetime warrantied"). Store manager was real piece of s^@t about it too - no substitution of even a lesser value.
Look at receipts too - note the numbers on the receipt don't match the item coding and descriptions are mostly cryptic. They don't honor warranties, don't issue refunds (more often than not) and have the integrity and good intentions of Charles Manson.
Do what I do and show your appreciation by voting with your wallet - and go to Home Depot if you want to deal with an honest company...
