I was looking for a new cordless circular saw and ran across this deal. Right now, at Lowes, if you buy a 6 1/2" Dewalt cordless saw at an already discounted price ($129), you get a 5 amp hour battery free! The battery itself sells for $179, so it's like buying the battery cheap and getting the saw for free. I just bought one awhile ago and couldn't be happier!
