The details about the transition are extremely murky - there was a lengthy and somewhat acrimonious discussion on another forum about this. Supposedly existing customers are to be grandfathered in - sort of. The minimum per order is waived and the amount per year to remain in good standing is reduced. I don't remember that amount - it is beyond my means as a hobbyist. Dr P also suggested that enforcement of the new minimums wouldn't necessarily be applied rigorously. Frankly the whole thing confused me. If you want to buy EOU oils, try to get in at the perfumery and see.
