This makes the best tortillas.  That is about all I use this for, so it lasts me awhile. Mine cost about 1/2 the price as listed here, but it was on sale where I bought it too.

Ex Output:
Positive


Ex Input:
The cookie is crispy good and flavorful.  The fortunes are thoughtful, not the shallow ones we are seeing lately.(Be patient, even in time an egg will walk)  I received the quantity and quality I ordered.

Ex Output:
Positive

I have severe diet restrictions.  All you who would like to be thin, I can recommend the IBS diet--as little fat as possible (I find I can take no more than 5 grams of fat in a meal), no dairy, no nuts, no chocolate, no caffeine, no decaf, limit wheat flour, no red meat, no heavy meals, no empty stomach, and on and on.  Deviate from the diet restrictions and you will lose weight. Eat carefully and you still lose weight.  This allows very few options when you eat out or you're on the road.  Since I work a job which requires a fair amount of travel in a large rural area, finding a 'nutrition bar' or snack food I can eat was a challenge.  Cliff bars are easy to find in most Walmarts, and cost just under a dollar each.  They're a little cheaper in case lots -- $5 for a box of 6.  I can only eat 2 kinds, and of course they're popular, so I seldom find them in boxes.  I searched online and was surprised to see Walmart.com offers an assortment of 3 boxes (18 bars) for $15.  They add $1.47 for shipping, but even so, that's a much better price than Amazon's offering here. If you like these, or have a lot of kids and family who do, you may want to check out that source.
