Input: Consider Input: Overall, the bags of popcorn were just like those that you'd get in a regular package of 8 or 12 bags. However, several bags did not pop correctly (or at all) and had to be thrown out. Also, many other bags would have a burnt hole after popping. I realize that some of this variability could be due to microwave wattage, but it was only bags from this large box of Orville Redenbacher's that would do this. I think when you order such a large box, your chances of getting "dud" bags increase...just something to keep in mind! Is it worth it to buy in bulk when more of the bags will be duds?

Input: Consider Input: These bars are just the right balance between the flavor of the coconut & the sweetness of the rice syrup. Unfortunately, although the expiration date is in 2013, about a third of mine went bad, or perhaps started life that way. They had a funny, metallic taste, & one even had some black substance on it, which may or may not have been mold. I'm wondering if refrigerating would have prevented this. I highly recommend these bars, but beware of the keeping quality!

Input: Consider Input: It is very good popcorn. But I used a hotair machine so may not have been as yummy as if the oily stuff had been used. Although I did pour oil on afterwards. Why would I do that with an airpopper you ask? Because the airpopper was a gift. I really can't tell a whole lot of difference in the taste from Orville R. and this, but what I have read is this is organic and much better for you. But the price is well...pricey. No I don't intend to buy again for that reason, but should my conscience tweek me towards healthier choice popcorn again then I may change my mind.
