tax rebate!!!

got home from work to a letter from the tax man....
opened it with nerves, shakes and worries, only to be pleasantly surprised.
455.20 tax rebate.
(cant forget the 20p, of course).
only question is , what to do with it?
paris, i think, after the madness of august, when ill be lucky to be gettting 4 hours sleep a night tops.
paris with callum in september-what could be better?
thanks mr taxman!
