I find that their oils are cheap. Do you have any advices?

Hi Cathy mm,

Quality may not neccessary be corresponding to retail price.   From crops harvesting till finishing products, bottling and export, it involved QC, test (
GC Reports and the numbers of traders in between..)were cost factors.  At the retail level, shop rental, employment and overheads needs to be considered.

Many essential oils are marked as fragrances or burning oils and many floral water were found synthetically produced.  Be aware.
