I am not sure what they do in case of water damage, but Apple stores usually replace the phone for $199 if you have a cracked screen or buttons that stopped working etc. If you buy AppleCare+ and have an accident, you'll end up paying $148, savings of only $51. If you do not suffer any damage, then you will end up paying nothing versus losing $99 with AC+. In other words, risk your $99, so that you may save $51 overall. Not a great deal.
