I live in Cairo, Egypt. I think you can find a lot of oil blenders in Egypt but I don't know if they sell good pure stuff or not, I don't have any experience with essential oils in general.
There is a region called Al Hussein in Egypt. There you can find a lot of essential oils and essential oils sellers.
Also in City stars complex, in the mall, you can find a shop that sells essential oils. City stars complex is famous here in Cairo.
Generally I don't trust those shops because they sell fake oils of designer fragrances. You order a fragrance and then they can sell you a fake oil for it or mix the oil with some alcohol and put it in a spray bottle for you. Of course the quality and the smell are far from the real designer fragrances, but designer fragrances are expensive in Egypt, at least compared to the economic level of most people.
