bizarre Big City Classic ticket pricing

[DeltaOne81]

I'm thinking of going, since its so nearby, but, this has really been confusing me:

Ticket prices for 2009 will be $15 for groups of 10 or more, $25 for Lower Level reserved seats and $40 for mezzanine Level seats.

Its been that way on sale for Ticketmaster for months, so it seems entirely legit. Has anyone who's ever been to Giant Stadium provide any rationale?

Mezzanine Level Yard Lines (229, 233, 209-213) - Rating
We rate Mezzanine Level (200 level) yard lines as the best seats in the house. These seats do not include the VIP amenities that you'll find in the premium sections of other stadiums around the league, but that's only because Giants Stadium doesn't offer many VIP amenities in any section. Mezzanine Level seats offer the best views of the game. Jets and Giants fans alike will be able to see every down of the action as the game unfolds.

Lower Level Yard Lines (129-133, 109-113) - Rating  
Lower Level (100 level) Yard Line seats are closer to the field than Mezzanine Level seats. Although you get less of an overall view of the field sitting down low, you're closer to the sights and sounds of the bone-crunching NFL action at hand. You really get an intimate feel for the game if you choose the Lower Level seats in Giants Stadium.
