I hate to tell you but ALL but three dates on her US 2010 tour through June are sold out, including Wichita. You can try eBay or your local Craigslist:http://tickets.shop.ebay.com/Tickets-/13��http://wichita.craigslist.org/tix/You can find a complete list of dates and locations, as well as which ones still have tickets available, here:http://www.taylorswift.com/tourpage.html
there are quite a few sites that you can search that will likely give you the best prices available. check out the website BookMe and you will be able to compare prices on all the reputable concert ticket sites in just a couple minutes. it s very convenient and will save you a bunch of time and money. Also, make sure you buy them online... otherwise they charge much higher fees for phone orders. good luck.
