There is an air show on near Oxford today (I know, short notice) and I bought a Groupon voucher for £20 that should have got a family of four into the show (normally £40). At short notice I need to take my father to the airport so won't be able to go. I'd be happy to email the voucher to someone if there is anyone locally who'd like it. Please call me asap, as the event has already begun and the airshow starts at 1pm. My email is [email protected]
