Sorry this post is showing up late in the day, but I've been super busy today.
Check out http://www.foodfacts.com.
It offers complete nutritional facts, health scores, and WW point values for thousands of brand specific products. I use it a lot, and I've double checked the numbers several times and they always match. I'd suggest checking it out if you aren't sure about an item you want to purchase or a product you've eaten. It's also great for planning meals.
