With the new customer offers you just wanna bet the amount you need to in order to qualify for the free bet. Like the betfred one, when you get the 30 quid free bet you should be looking to get 21-24 quid from that, depending on the match you're able to get. The higher the odds the more retention you get, for example if you get a 4.0 back bet and 4.2 lay bet, you will get a lower return than if you get a 8.0 back bet and 8.2 lay bet match. You should look to try and get 70-80% from the free bet amount. For qualifying bets, good matches start from about £1-£1.50 loss per £25 bet. So if you're looking to place a qualifying bet and if the bet you're making is £25 and the calculator says you will lose £3 no matter the outcome then find a better match. The new customer offers are the most basic of offers and if you had a lot to do you can build up a small bank. My advice will be to do as many as you can and go to the PS forum for help and guidance and check the calendar for daily offers. The guys on the site are very helpful and will be more than happy to help should you have any questions.
