Horse racing costs £0.50 for all races at a meeting. The data includes win and place markets. So all you need to do is multiply £0.50 by all the race meetings in a year.
You won't, however, be able to order a whole year's data yet, as only the last few months are available at present.
Time Machine costs £6 per month, but if you take out a new subscription to MFPro by 07/01/14, TM is included free for the subscription period.
