If you just want to slide around the hill and don't really care about techie thingies just ski them. The money you save can go to beers.
If your technique is strong, and/or your feet sensitive, have your shop check the bases for flat, and edges for the correct angle and have them fix these if they need fixing and wax the bases, they last longer and the ski turns much better with wax.
Mass production makes for poor quality control. Even then, many skis arrive with a zero-zero edge which is great for mountaineering, but not all that fun on-piste.
I got some new Volkls with a Zero base(not fun at all), the first shop couldn't grind one degree on the base so I went to the competition with the glidewell system and got my requested 1 and 3 grind.
If you are of the first grouping, ride them hard and put them away wet, be proud that you never had a tune and can ski the pants off the techie, just beware that those sticks will not last very long and the beer budget will suffer when you replace them.
