Sign up to betting site Ladbrokes and when you deposit and wager £10, you’ll get £36 cashback from TopCashback. Thats a massive £26 profit, or even more if your qualifying bet wins!
You could also look into ‘Matched betting’. (See Profit Accumulator NoBrainer for a further £5). Although slightly complicated, you could use some clever maths trickery to make your initial bet almost risk free. Do remember that this one is about free cashback though, and not silly gambles!
Please note, if you have previously signed up with Ladbrokes or Coral, you will not be eligible to receive the cashback.
