Reasons to purchase in a store are clear, you can hear and see the speakers and you can walk out with them that day. Purchasing online means you have to possibly buy the speakers sight unseen and you have to wait 3-10 days for them to arrive. Most online resellers will allow you to return speakers if you don't like them which is a plus. Most even pay return shipping. Also listening to speakers in your own home really DOES make a BIG difference. I recently heard a pair of bookshelf speakers in a big showroom and picked up a pair just to prove the point to a friend. In the store they sounded thin with little mids. When we got them in a living room the high's seemed to fade, the mids came up and the bass was loud. Too loud. We had to move the speaekers around to optimize the sound and cut the bass by 2db.
There are quite a few reputable online speaker resellers out there that have great sounding spekaers and lots of help in the fourms to help you choose. You should not have to pay alot for a quality pair of speakers. Look for a good pair of 6.25" bookshelf speakers to set you back $200 - 350 and a decent center channel at around $125 - $150.
