I check mine every couple of weeks and have to adjust 1-2 pounds consistently, as all tires will seep air. The best suggestion so far is to replace the air with nitrogen, but that will cost you a few bucks.
But...I have one more (maybe ridiculous) question. Do you have a good/accurate tire gauge that you are using? Those .99 specials or the built in ones on the air hoses at gas stations can be off by more than 5 psi. If not, you may want to check into something like this:

By using a good gauge and checking every few weeks, I have never had a TPM light in the year and a half I've owned the car.
