Not long. I bought my Gills tickets 3 weeks before the game, when they hadn't arrived the day before the game I went to the Amex for replacements - they then turned up in the post on the day of the match!
I ordered my Blackpool ticket online 10 days before the game-it still hasnt arrived ! I phoned the club on Friday (day before game) and they told me to take email in to ticket office-Saturday morning still no ticket and got to the ground at 1.30-the que outside was horrendous but explaining the story to the steward on the shop door he kindly let me in. Just hoping my Peterborough ticket arrives ?
