I play the UK Lotto through the E-Lottery online which basically costs £5 to enter the Wednesday/Saturday UK Lotto draws with 44 ines on each (prizes divided among a syndicate).
The main advantages of this from my viewpoint is that
1) Don't need to buy/check tickets, work is done for you and results sent via email.
2) Only need to match 5 of the 6 numbers drawn to win share of a jackpot (one is guaranteed every draw).
