tennis balls (Whittlesey)

I am looking for tennis balls, any old balls you have stored or your not sure what to do with them, I can make good use of them, if it's a very local collection that's fine if it's on a small amount, however n please don't think I'm being too fussy! it's the fuel cost, for larger amounts 10+ I am happy to travel within an 8-10mile radius of PE7
