Idk. I usually give the money to my mom, she buys a iTunes card. When I use it, I get no tax when I buy games and music. Maybe when she buys it at the cash register (obviously) they tax her like a Dollar or less
I just picked up Rock Band the other night at its sale price and i gotta say i cant put it down...The song selection is a little limited but im sure more songs are to come...Good game for 6.99. Warfare Inc. is IMO amazing for 4.99. An RTS that feels very much like starcraft with (also IMO) very good graphics and amazing controls. Peggle...Nuff' Said. Like someone else said Nick Chase is a very fun pick up and play app at a great price at the moment. Or if you like Tower Defense games Coastal Defense and Defender Chronicals are very fun. I've been wanting to get 2XL Motocross because the lite is fun and the 2XL games are beautiful (Better graphics then some like genre PSP games) but havnt gotten around to that one yet..
If I were you I would definitely not buy touchgrind. There have been very few updates and it just ends up becoming extremely repetitive. Go with Cliffed!
Heads will roll, Blue Defense,Blue Attack, Meteor Blitz, 33rd Division, Aqua Globs, Airport Mania, Mr Aahh, Soosiz, iBlast Moki, Parachute Panic, Tribe war, Galcon Labs. There should be something in that list to help you spend those last few dollars.
The only upcoming games that I think are worth getting are Zenonia 2, Chronicles of Inotia 2, Ravensword, Nova, and probably Twin Blade, based from the "upcoming games" forum threads (not sure of other worthy games coming). As for current replayable games I'd suggest Beatrider, Zenonia (though with the new update they significantly lowered drop rate to the extent that enemies will rarely if ever drop anything), iBlast Moki, RTK Touch, NFSU, and perhaps Alive-4-Ever. I wouldn't get Bloons TD if I were you. The game has like no challenge (at least for me) for the main game, and the endless mode is stupid in the fact that you can lose all 100 lives in a matter of 2 seconds, since hundreds of balloons are stacked together.
