I did a comparison (it's probably on here somewhere) of match-day prices for a specific game against someone like Stoke or West Brom and compared it to what you'd pay at other grounds to watch the same team. I'll look for it later (I'm just going out) but the results were quite surprising. It's hard to compare season tickets on a like-for-like basis as certainly Spurs and Arsenal include some cup games. The basic package at Spurs gets you two free ones and at Arsenal you get the first seven games free.
Cheers for info. From what I've read I always believed Arsenal had the most expensive tickets. Far more expensive than ours. I suppose it's use & abuse of statistics!!!!
