It's a good time to be buying as hopefully people will have come home from the series with a lot of $ they wanna shift, so it'll be a mutually beneficial deal so should just do it at spot rate (the rate you get on xe.com). This will save both parties getting screwed by the high street.
You'd wanna meet someone who lives near you or you could meet up with easily, otherwise spending too much on transport costs could defeat the object of beating the high streets.
any realism about?
