The last few years in the lead up to cheltenham if you bet 40 or 50 a week you qualified for tenner free bets for Cheltenham week on exchange. Think it ran for 4 weeks so you could build up a small 40 euro/pound kitty to use cheltenham week on the EXCHANGE. Seems like this has been pulled this year and some complex multiple is required to be done which can only be used on sportsbook, a much reduced offering - further tight fisted penny pinching from Betfair/P Powers
