Chelsea and Man Utd - a sure bet this weekend? Your money back if we're wrong! Right now you will get your stake back on the first three lost combi bets on Betsson Sportsbook. This is how it works: Everyone registering using the link below before 2010-03-31 is entitled to this bonus. You will get your stake back on your three first lost combi bets. A combi bet is a bet with more than one selection in the same bet slip (bet slips with several single bets don’t count). The maximum amount that will be refunded on your account is 25 EUR or 25 GBP. If you are betting a system bet all bets on that system need to be lost in order for you to get money back on that bet. Note that lost single bets won’t be refunded. Register your account here!
