I so wish I would have read this review before purchasing TWO gallons of this oil for my health issues. It reeks like a chemical rubber smell. This smell is coming from the black rubber gasket in the lid. When I called to report the situation to the company, Sabrina told me I would have to pay to send them a sample to have tested by a lab. Unbelievable. Good customer service would indicate that they would pay for the product to be returned and give me a full refund, including shipping. The product is faulty. Period. I will never order anything from this company again and do not recommend it to anyone based on this horrible customer service and lack of responsibility and ownership.

With any low fat or low calorie food, you're going to sacrifice taste of portion size.  With this product, you sacrifice both.  It's a good idea, which was done well with the Oreos and others in this series of "100 calorie" snacks, but I think you're better off with a single cookie from the regular Chips Ahoy box than a whole bag of these.

I love Community Coffee but the batch I received of the Special Decaf was old the bags had lost their vacuum packed state.
