I buy my batteries from Persula, they are the cheapest, they are a charity and sell them to make life easier for us, they sell many other products like c d's, cassettte tapes etcetera. You can pay over the phone with your card. Their telephone number is 02073579298. They have a catalogue on C D of the products they sell. Vanessa the Google girl. Skype name = RainbowStar123
