What are some good Facebook promotions?

[Travis]

I finally got talked into starting a Facebook page for my business and was wonderring about some promotions to do. I am fairly new to Facebook and so far have only used it to show some new products, basically a picture and a discription. Any ideas, help or comments are welcome.

1. How can I go about getting more people to "like" my page?

2. What are some good promotions you have seen ran by other business's or your own.

3. Any other ideas?

A little background:
My business is a smaller sporting goods store specializing in Firearms and hunting supplies. My current market is local in an area of less than 25,000 people. My sales are right around $500,000/year and climbing about 10% over the last 4 years so I am expanding and keep looking for ways to expand further.

I greatly appreciate any help.
