There's a lot of free holiday money available this week with bookies competing for new and old customers. Skybet have a very good one offering a free bet up to 20 if your bet on the first race every day goes down - if you're in to matched betting and have a lay account (eg Betfair Smarkets etc) that allows you to lock in a profit of c60+ for the 4 days. Betway have something similar (up to 20 of free bets a day) as do Bet 365. And if you are a new customer there's even more to be had.
