Seen this scheme that Budweiser are running? Buy a voucher to use at a participating pub and Budweiser will match the value with a free voucher (and you don't have to spend it on Budweiser!!). There are only seven pubs in Cambs taking part at the moment, two are in St Ives and there is also the River Mill in St Neots.
