Example Input: I had read some favorable reviews of this pancake mix on Amazon quite a while ago.  I had never ordered any, but I came across a can of it in one of those outdoor,camping stores last Christmas.  I have been using it ever since to make my dieting harder, and can honestly say I have never enjoyed the struggle so much.  Pancake mixes are usually one of those things that usually I buy the cheapest I can find, or at least one that I am familiar with.  I tend to balk at higher priced mixes for the most part. But every now and then I get curious of a brand like this one. It just so happens that when I visited this camping store, I was getting ready to take a short hike as soon as the holidays were over, and pancake mix has always been one of my staple items to take along.  Unfortunately it wasn't 'till I left that I realized that this mix was not one of the "just add water" ones that we all know and love.  The best ones always needed your own addition of eggs, milk, butter, etc, and this one is no exception in that respect.  So instead of enjoying this mix on the trail, I have been making pancakes in the wilds of my very own kitchen.  I really don't know what it is about this mix that makes it so good, but it does indeed make some of the best and most delicious pancakes I have ever tasted from a mix.  They are very light, fluffy, and flavorful, and well worth the price and ingredients that you have to add yourself.  If you have a pancake fiend in your home, I would highly suggest you buy some of this great mix. Its cheaper here on Amazon than I paid for it and well worth it in my opinion. I have had lots of different kinds over the years, and this makes some truly delicious pancakes.... Highly recommended...

Example Input: I just called Bob's Red Mill customer service (just do a G search for the company, their customer service number is under "contact us" on their site), and I was annoyed to learn that NONE OF BOB'S RED MILL BAKING SODA CONTAINS ALUMINUM. I've been paying $10-15 (with shipping) for this magical 'aluminum free' baking soda only to learn that the Bob's Red Mill 'premium baking soda' at my local grocery is the same exact thing. Call for yourself if you don't believe me. Ugh.
