Yes you can use facebook to promote business, but then, consider the "policy",and also you must be creative if you choose to use it, because at present, there are a lot of people using it. There are more sites, but facebook is one of the best for me.
You can make fan-page of your main company there you can display your products but creation of direct pages of your products can create problems for your business products! so the best practice is to promote your own company that can automatically promote the products.
you can promote your products you can even create an shop with your Facebook fanpage. Like this pizza shop you can add your products so get sales directly from your Facebook fanpage and generate reviews from your customers.
Yes you can promote your product because Facebook is a Social Network and anyone can access it for free.

Yes, you can promote products on fb. Depends on how you promote your products. Just be careful not to overdo it nor violate FB's terms of service.

Facebook is best for promoting products. The best way to promote and get traffic is creating your own page.
