Ex Input:
We received a gift box that contained the Stonewall Farms Pancake Mix and they were out of this world. They are the lightest, fluffy and flavorful pancakes and waffles you will ever taste.  And the price on Amazon is a big savings over ordering from Stonewall Farms.  Don't shy away from the larger size and the two pack because you will devour these pancakes in no time.

Great product, nice combination of chocolates and perfect size!  The bags had plenty, and they were shipped promptly.  The kids in the neighborhood liked our candies!

I love these noodles.  They are really great for a midnight snack.  It's not really something that will fill you up for a dinner.  If you do eat it for dinner, you will be hungry later.  Maybe some people wouldn't!!!!  But, it just doesn't stick to my ribs.  I love them though and Amazon has a really good price.
