THE DEBUT of Boro's online season card renewal facility is proving a huge hit with fans.

More than one in three fans who have renewed their cards already have done so online.

Existing adult and over-65 season card holders have until 7pm TODAY Sunday (May 11) to take advantage of Earlybird prices for 2008-09, although they can retain their current seats right up to the renewals deadline of June 28.

Those who wish to retain the same seat can renew online here on the website.

Season Cards can also be renewed by returning application forms by post or hand to the Riverside ticket office or fans can simply take their 2007-08 Season Card into the Riverside's main ticket office and let the club do the rest.

The £95 offer for all those aged under-18 is available for renewals and new applicants in all areas of the stadium through to June 28, as is the £195 price for 18 to 21-year-olds in the South West and North West corners.

Additional season card packages, including a DVD and application form, are available by calling the Riverside ticket office on 0844 499 1234 or email ticket.office@mfc.co.uk.
