I just browsed the sites of two online shops we have here, and they do had some oils, but not what I was looking for. I'm sure you have something similar in the US. I don't know what to call such shops, but it is shops that sell food, candy and often other things, electronics, clothes etc, goods that are short dated, from bancrupt stores, surplus goods and that sort of things. They sell at a reduced price, and they advertise that you as a consumer can contribute to lower food waistage, for example. They often have very good prices, often half price or around there.
I was looking for 1 particular kitchen timer, found it and ordered it from one of those stores. It was so cheap (well under half price) I had to by three (two for multitasking with different things cooked or baked at the same time, and one as spare). At that price, it was most probably timers bought in from bancrupt stores. The groceries they have are not always short dated. It depends on where and from whom it is coming from. And they often sell goods in bulk.
If you find stores in that category, you might do some real bargain buys on soapmaking oils!
