They are smaller than a credit card, will fit in a wallet. I'm gonna try the petrol station round the corner first actually, they probably sell batteries and wont be a big walk into town, if not then the coop a little bit further away.
Maybe I should sample my friends drugs to make sure they are not poisonous, that could be a good idea, but I have the dentist at 4.30pm and I need to go to the post office today too, which also luckily is just a short walk away.
