Just stick to 3/4 team accumulators and stick £5 or £10 on it. Don't waste your time with silly 9 or 10 teams and putting a £1 on as they very rarely come in. In the last 3 weekends I'm in profit of £145 by doing 3 team bets.
Also always keep an eye out on bet in play you can sometimes get really good odds in some games.
