Got my axles, struts, brakes, radiator, distributor cap and wires, and fuel filter from Napa, master cylinder from Pepboys, motor mounts from Autozone, oil/filter and other fluids from Kragen.
Since i'm cheap, i get the remanufactured parts

...the only problem so far was one of the axles started clicking after about 8 months of use, so I returned it (within the 1 year warranty period) and they gave me another one, no questions. As long as you do your research before buying parts, most auto parts stores are reasonable.
I don't have a preference...(ok maybe Napa b/c they give me the AAA member discount) and as long as you can find a store with people who have a general knowledge about cars, you're alright. If it's and emergency, or i just dont have the time to do trial and error part fitting (i.e. Napa), I run to the closest non-napa parts place.
Hell, if you have a good connection or are just
dying to spend on ur Camry, go to the dealer. I got to know the parts manager at my local dealer when I started fixing up my Camry and he would give me a really good break when I came in (think OE parts for non-oem prices). Dealers usually take other dealer coupons if you get them in the mail too.
wow, didnt mean to write an essay, but hope this helps
