Costco here as well. I've picked up pomace a lot Mediterain (sp?) grocery, but I think the price wasn't quite as good as Costco. I'm not sure if the Soaper's Choice price is better, b/c Costco is by volume and SC is by weight and I've never gotten around to weighing my Costco oil and doing the math. I'm sure that if you are ordering the 35 gallon cubitainer, the SC price is better. I order stuff from SC that I can't get at Costco for good price. I just ordered coconut oil, cocoa butter, shea butter, avocado oil, castor oil and stearic acid.
I've always wanted to order a cubitainer. No reason. Just because.
