Hi becca90 !
Apart from the Fan Card option, if I were you I would join your nearest Branch of Liverpool Supporters who will be running a Coach to Anfield for every Home Match. They will have been allocated a certain amount of Tickets for each game as was the case with the Branch I belonged to.
I have attended hundreds of Anfield games over the Years mark01, but have been priced out of games like many other Supporters.
There are around 60,000 on the waiting list for Season Tickets, Fan Card Holders number thousands as well but get priority when applying for Match Tickets.
Best of luck becca90 and if you are lucky enjoy your Anfield experience!
