For your purchase, try searching online. They offer much better deals there than most in-store locations.
Recommended stores to look at:
When deciding which camera to buy, ignore some of the marketing gimmicks they advertise such as megapixels, effects, and the extra lenses they throw in.
Megapixels: as long as you have above 10.0-12.0 megapixels in your digital camera you'll have more than necessary... Unless you're a professional and you make VERY large detailed prints.
Effects: these are sort of a waste since you can do all of this stuff later in a photo editing application like photoshop.
Lenses: since you are just starting out, I wouldn't be too concerned about this; however, If you plan on getting into photography more in the near future, then it may be wise to consider that the glass (lens) you choose is just as important as the body. As an intermediate-professional photographer it would be wise to spend (more or less) 50% $$ on body and 50% $$ on lenses. *This is why they sell some camera models as body only* But, since you are just beginning, the 18-55 lens the body usually comes with should be ok for now.
Things to consider:
Features that are important to look for in the camera (depending on what is most important to you) are ISO range; burst mode fps (if you want to shoot sports or fast moving subjects); the option to shoot video (HDSLR video is getting quite big nowadays!); the size of the camera and layout of the controls/buttons (whatever you prefer); and if it matters to you, the LCD size.
There are other features, but probably ones that don't relate to your buying options right now...
I recommend even looking on craigslist for cameras and lenses that people are selling. Just make sure you find out how much wear they've had, number of shutter actuations, and how old they are.
