I note that the price of $15.97 for 4oz is very (maybe too) reasonable. How is the product able to be sold so cheaply if it's indeed 100% pure?

Hi Alex, 15.97 is a very low price for good quality Pure Moroccan Argan Oil. We are currently running a sale to get customer feedback, and to give people a chance to try our product at a reduced price. We know you will love our produts, and will be a happy customer for life. The price won't be at 15.97 for long though, so dont be suprised if you see the price much higher. Have a wonderful day!

Is it glass or plastic bottle?

Hi Jade! It's a glass bottle. Hope this helps you.

Why is this product not eligible for Amazon Prime?

Hi AB, It looks like an inventory issue at amazon, but should be available again in just a day or two.

Does the product contain alcohol?

No, it is 100% pure, and works very well. This is a great product, but they recently doubled the price of the product. It used to be $15, and I suggest you buy from essential depot(they are on amazon, too). Their argan oil is about )$15, but it is not organic. Hope this helps!
