I signed up for a free online account with 'BetFred'
http://www.betfred.com/There's several different lotteries with various odds you can select to play.
I use my paypal account to put funds into my betfred account to pay for my bets.
Now I've had a win, I've given my bank card details to them so £650 can be transfered directly to my bank account.
Never had a problem with them in the 2 or so years I've been using them.
