Compared to my local health food/herbal store:
I bought 4 ounces of almond oil at the store for $8. Piping Rock had 16 ounces for $4! Of course I had to order a 16 ounce bottle, as well as 16 ounces of grapeseed oil for $8, (compared to the store's price of $13 for 4 ounces).
I make beeswax soap and beeswax body bars, so I am very familiar with different brands of essential oils. My order from Piping Rock arrived within 5 days, was packaged sloppily on the outside, but what I cared more about were the products on the INSIDE of the box.
I compared Piping Rock essential oils, side by side, to the essential oils from my local store. There was no difference in scent, viscosity, color, and all had the same pleasant feel upon my skin.
Now I'm going to try using the $10 coupon I received with my order, and if it is not honored (as one customer said in an earlier review), my opinion will be subject to change.
