It's the same on Sky as you have to buy it direct from RUK rather than as part of any package. Can't believe RUK will last too long if they keep trying to charge that much.
Racing UK is now a standalone subscription channel since Setanta went bust. £20 p.m. was the price before it went into the Setanta package. They only have around 100k customers anyway so possibly could end up merging with ATR and become a free channel as they will then be supported by the red interactive betting button bringing in additional revenue.
