I've always dabbled with free bet and sign up promotions, but the Profit Squad sticky did focus my mind and for the last couple of months I have been using my spare time productively.
I took the one months trial and had a hunt around their website. After a day or so it was clear the 'paid for' information was readily available for free by simply using Google, including the matched betting calculator.
I had accounts with most the bookies, but I did sign up new ones with Coral and Bet365. In addition, I already have Paddy Power, Ladrbrokes, Will Hill and Sky Bet.
I'm not interested in Dutching as this does carry some risk unless you are prepared to offset it by investing a lot of time for a small return. I will take a free cash casino offer when they are made available but I've not taken any with wagering requirements. I have no doubt some of these (including Bingo) are profitable, but are not without risk and as my time is limited I have decided to stick with these bookies and the offers I know.
If you don't have any of the accounts I mention above, then there is a good £500 to be had from the sign up offers. On an ongoing basis I limit my matched betting to the following offers, which in all takes me about 2 hours a week.
SkyBet: Near daily money back if you horse finishes 2nd and sometimes third. You can normally wager £25 on this and if the lay odds are close you should be able to match the bet for under £1 loss, with a £25 bonus if it's 2nd or third. There are times when you can lay it for no loss at all
Also, they have frequent extra place bets. Again, these can be laid for a minimal loss and can pay well if you are lucky enough to have a decent priced horse come in the extra place.
In addition to all, there is a £5 free bet for wagering £25 a week.
Ladbrokes: A TV football game will often have a free £10 bet in play when you bet £25 pre match. Odds are very tight on TV games so you can lay this for a very low cost and lock in a small profit. I would recommend placing the inplay bet at half time to avoid getting caught out by fast changing odds.
Paddy Power: these have similar offers to the above two as well as some other interesting ones that are usually profitable
Coral Bet: Their double your winnings offer on some TV footy games is great. The maximum extra is £100 so place a bet on the team you think will win to make exactly £100 profit. Lay it off. Again there will be tight odds so the matched bet should cost no more than £2. If the team you bet on happens to win both halves, then you will win £100 for a £2 risk. My most recent success on this was the Spurs v Chelsea game last week. In addition, there is a £5 free bet club. You have to opt in each week and the free bet has to be earned Monday to Thursday and used that weekend, so it's more restrictive than the Sky Bet one but money for nothing.
Will Hills: This is my bookie of choice if I have a lazy afternoon and there is racing on They usually have a meeting where if your Horse wins by 5 lengths you get a 25% win bonus up to £100 and if it loses in 2nd by 5 lengths you get your bet refunded up to £25. Not loads in this but over the course of a meeting, you should get one or 2 hits.
Bet365: Decent various offers and reload bonuses that are easy to work off. On top of the £250 sign up bonus there is a further £50 for using a mobile device
I'm not interested in trailing the web for every offer. I'm also not going to put time into get £5 free bets, of which you might only realise a £4 profit.
If I'm missing any obvious decent earnings that are not time intensive, please let me know
