Tickets for next year's Glastonbury event will go on sale at 9am on October 5.
Glastonbury festival-goers are being given the chance to purchase an unlimited amount of tickets for next year's event.
Fans will be able to buy up to six tickets before being given the option to book more as long as each purchase matches a valid registration number.
Registration for the three-day event has already opened and tickets will go on sale on at 9am on October 5.
Glastonbury 2009 will be held over the weekend of 26-28 June.
A spokesman for the festival said: "Lots of people have wanted to come in groups over the last couple of years and they haven't been able to.
"But the registration system has worked so well and we have the security in place to give us that option this time. So people can buy as many tickets as they want."
Despite the new plan, festival-goers will only able to use one debit card per transaction.

Fans can make a purchase by putting down a deposit of £50 or by paying the full amount of £175 when tickets go on sale.
The remaining balance must be paid by 1 February, 2009.
Up to 100,000 tickets will be made available in October but a second batch of tickets will also go sale from 9am on 5 April 2009.
Each registration number will also be saved this year so festival goers will not need to re-register for the next four years.
Glastonbury co-organiser Emily Eavis has hinted that she would like Radiohead, Coldplay and Led Zeppelin to headline next year's event.
"Coldplay are a great Glastonbury band, as are Radiohead, but it's really hard to say at the moment for definite who's going to play next year," she said.
"It would be really good to have an appearance by Led Zeppelin too, that's one band who haven't played here."
