Sorry I was quoting a gallon's price on the castor oil, as that is less expensive by the pound. But even with the supposedly free shipping at wsp, columbus oils are still cheaper for me. Their shipping is quite reasonable, although it certainly will depend upon where you live. They do have a shipping calculator on the site though, so you can check it out before you fill out any info (I hate the ones that make you fill in all the boxes before you can get the shipping cost!). It certainly wont hurt to check it out and compare. And Bayousome does have some good sales at times, and some decent prices too, but they are limited in their selections. I do like the price for their seal and lid combos though. And if you join their mailing list you will get a link to a secret sale page that you cant see or access without having the link. Those deals are usually quite good.
Much luck in finding what you want at good prices!
