When opening an account to take advantage of a bookmaker’s free offer, you can open as many accounts as you wish, as long as you use a different credit card for each. Also, if you ever have an account closed, have a friend open one up with the same company. None of these actions are actually bookmaker friendly, but, like them, we must always look for an edge in our favour. Or better still, use the betting exchanges and win as much as you like!
