Check that the oil filter has its gasket in place and is screwed in tight. Also, sometimes those oil changing places remove old filters without removing the old gasket. They then screw in a new filter with a new gasket, which makes two gaskets that will certainly make a leak. And make sure the filter doesn't have a hole it.

If all of this checks out ok, check around the perimeter of the oil pan. Maybe there's a leak in that gasket. But if you're using 2 quarts a day, I'd suspect the oil filter. (I'm not sure if you engine has an aftermarket oil cooler. If it does, you'll need to check the lines for a leak.)
