it's not too bad in the U.K. It's £6.03 - £6.67 (£15.85 - £17.50 for 2100 points).  $11.60 does seem too much. try looking on the internet for instant-access codes (they are e-mailed to you <2 seconds (seriously, i got 1  the day after the maps came out) and they  are much cheaper because you don't pay for postage & packaging)

 Map packs are far too expensive - I bought 'Splosion man for the same price as one and last year i bought Castle crashers for 1.5 times the price.  If a full game can be sold for 800-1200 MSP for a profit, then why can't maps be sold for less? surely it cost more to make a full game than 3 maps.
