Example Input: While I have not purchased this from Amazon I have used it for many years.  It makes a super layer for, my version, of Zuppa Engelesia and mixed with cream can be incorporated for Pate Choux. I don't live in Hollywood any more so it is getting more difficult and thanks to Amazon I find it it available and in larger cans.........  I plan to order soon.

Example Input: 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.

Example Input: My subscription of popchips arrived on time and not damaged.  I love the fact that I receive a great variety of chips which are healthier and at the same time very tasty and satisfying. The way the chips are packed for shipping is perfect! Having a subscription is the way to go and of course the price is so right!!!  Thank you,
