It may sound as if I'm too lazy to find this stuff on my own but that would be far from the truth. I've been to a bunch of stores and searched the net for a retailer. Nada. I think shopping on the net can be great but so is supporting local stores and the convenience of being able to purchase things without shipping.
I looked all over for it, too, with no luck. So buy mine online from Super Supplements (they're local to me here in Seattle, but their retail stores never seem to have MCT oil on the shelves). I buy enough at one time to qualify for free shipping (four quart bottles at ~$14 each), and while that sounds like a lot, I go through it so fast it's worth it. As soon as I crack open the last bottle in the cabinet, I order more.
