Summarize the following:
This will increase your safety and make for an altogether more enjoyable experience.  Start asking around when you hear about the show. Coordinate who will buy the tickets since buying them individually will mean you sit apart. (Unless it is a general admission show.) Keep in contact with your friends after you've decided to go. Make sure no one changes their minds or makes other plans and you buy a ticket for them. Either go through the venue website, the band website, an authorized ticket website or authorized ticket site, such as the box office. Compare prices between websites to confirm you are getting your tickets at a reasonable price.  Booking online or in person will offer you the same chance for good tickets. Spending the night outside the venue no longer offers the opportunities for good seats, unless general admission for this venue means standing room close to the stage. In this case, the earlier you get to the venue the higher the likelihood that you will be front and center. Find out the date and time tickets go on sale and try to book at that time. Online sites may offer bad seats for your first search. Unless the show is a guaranteed sell out you can usually refresh the search a few times and find better tickets. If your under 18, have a parent or adult guardian purchase the tickets for you, this doesn't have to mean they spend their money, you can pay them back. Buying smaller numbers of tickets will usually result in better seats. Trying to buy 10 tickets at once will probably have nosebleed seats. Purchases online require a credit card. Box office purchases can usually use cash or credit. You can avoid some fees by getting an e-ticket that you can print. These are easy to duplicate and since you don't know if it's valid until it is scanned people may shy away from buying your ticket should you need to sell. Most venues offer "Will Call" service. This is when you buy your ticket and have it waiting for you at the venue for pick up.  Will Call will require you show a driver's license and the credit card used to buy the tickets. Most require the names match on the credit card, the driver's license and the name the tickets are being held. You should avoid waiting until the day of the show to pick up your will call tickets. Lines will be long and you won't have time to correct a mistake (such as your tickets not being there but your card was charged). Picking up your tickets from Will Call ahead of time also gives you an option should an emergency happen and you must sell your tickets on short notice. Since the buyer can't pick up your tickets from will call. The Will Call window is usually open during the box office's regular business hours and extended hours the day of the show. Smaller venues may have later hours and not offer Will Call service. Call and ask before you assume.
Encourage friends to come along. Book your tickets from a reliable company. Select the method of delivery that works best for your timetable and situation. Avoid auctions unless you are willing to risk counterfeit tickets or paying high prices plus shipping.
