If you really like citris oils, they tend to be the cheapest of all the EO's. I buy by the pound and it helps with cost a lot. Go check out New Directions Aromatics, that's where I got my first shipment of EO's recently, they package everything really well and the EO comes in big aluminum bottles. I cant remember the price of 5x orange right now, but I know it was under $20. Ditto cedarwood, and several others. Start off with a few that arent such a huge investment. I'm having a lot of fun using FO and EO both now.
