Before I buy oils I price check with shipping across several suppliers. I think it was Jedwards that Lin sent me to that I bought from, it was cheaper than soapers choice once I factored in shipping. I just had to decide if I wanted a 2 year supply or a 1 year supply - not having to order again and pay shipping again won me over. The shea butter should keep well. Of course, that was just my experience based on what/how much I was buying and where I live.
My point is that rather than take everyone's "say so" on what is expensive shipping, check out the recommendations for yourself for what/how much you need and make sure you factor in the shipping, then break the total cost down by oz/lb. Sometimes a place that seems to have high shipping, actually ends up being the cheapest.
