Very rarely, if there's a mahoosive jackpot. I do it online and any winnings stay in the account to be used for the next one, I haven't had to put any money in it for a looong time.
I rarely buy tickets in the shops anymore, but do have a subscription for £2/week on the saturday draw.
I've only won £10 4 times in 6 years, although each one was a heart stopping moment when I received an e-mail from them telling me "They'd exciting news about my account"
Two tickets every draw set up via Lotto website for the last year. £60 won in that time. Sometimes have a go at Euromillions. I did win £2500 on fixed odds coupon at the start of the season.
You do know there is a PH syndicate dont you? Even got a hidden forum where there are dancing girls and free booze and basically just filthy behaviour from very rich winners.
