Are they still on sale? and if so for where in the ground?
Have you tried looking on the club website?
http://www.seagulls.talent-sport.co.uk/PagesPublic/ProductBrowse/productHome.aspx and Under 5 match package
Looks like the only blocks available are S1H & W1I (don't know if the new seats in the North corners will be available for this deal once ready?)
Yep a bit weird that only those are available. Surely they should be selling the corners as well for this?
