Wal-Mart or Best Buy would be great choices. At Best Buy you will have more selection, but at Wal-Mart a consumer is probably going to pay a lower price.
Best Buy has a wide variety of GPS systems, and offer a fair and unbiased shopping experience. If you have a smartphone, read your manual. You may have a GPS built in!
http://www.bizrate.com/global-positioning-systems-gps/ is a website which compares GPS units and has very competitive pricing. The only stores which will sell GPS units exclusively are the distributors of a specific brand, which defeats the purpose of comparative shopping.
The best way to check fair pricing is to go to or look up on the internet, the pricing of several stores and compare to see where the best deals are. Some even offer "compare" spots on their websites to help you compare to other products.
