It's usually about £50 ish for GA and of course the dreaded "booking fee". I would imagine that the $140 would be for a specifically reserved area at the front so would therefore be more.
But the cost varies with venue and seating arrangements, etc. Just try to get them from the official channels before they sell out otherwise you are talking mega $$$$$$$$ (as I found out booking for Madrid). Unless you know a generous coldplayer on here......
I am watching for news of dates of this in particular!!
