the membership's benefits for me are the ability to get tickets before they go on general sale and then to get them in the family area in the east stand where the seats used to work out a quid or 2 cheaper than the north east corner.
considering that getting tickets in the NE is a bit hit and miss, as it sells out fairly quickly, and you get a slightly better view of the match, IMO, from the magnificent new east stand then it's a reasonable deal. i can also get my lad tickets,

which is a bonus but the trouble is you've always got to ring them up and go through the tribulations of waiting for ages while you pay through the nose to sit in a queue
but instead of sitting with a bunch of old miserable sods, which is what i like in the NE,you've then got the pleasure of being surrounded by other kids and their families.
