Instructions:Title says it all.
Register for a BlueSquare account (or if you already have one it will still work)
Go to "My Account", Click Free Bets, and then enter june7 (Make sure it's lowercase).
Your account will then be creditied with a free £3 bet to use on the Derby at Epsom today, or for a Euro 2008 market.
It will show in your account as a £6 free bet, this is because you can either have £3 on the Derby, or £3 on the footy.
Note: BlueSquare isn't on any cashback sites, so you won't be able to take advantage of that too.
