A little trick I like to pass on regarding good seats and concerts. But you have to be a gambler at heart (or not really care if you go or not)...
Wait til the day before the show. Maybe 2....yea, start at 2. At 10 am or so, a chunk of AMAZING seats are usually released for sale. Usually, but this is in no way guaranteed to happen. That's why you need to be a gambler to do this! But I know for a fact that this happened 2 years ago for my AI show. Went into Ticketmaster the day of the show and there were seats right next to the stage (high-fiving distance) available for sale. They are saved for VIPs or family members or whatever, then released when unused.
