I use LostGolfBalls.com and GolfBallsDirect.com. I normally get the 5A Pro V1's. I got 4 dozen at Christmas from GolfBallsDirect.com for about $23 a dozen. I've never had an issue of playability and losing one in the woods or water is not as painful. I've also tried Bridgestone Tour B RX and at much cheaper prices gives me the opportunity to try new brands. I had an issue once with LostGolfBalls.com order. The balls didn't seem to be the 5A that I paid for. I contacted customer service and they sent me replacements of the ones that were not what they should have been.
