Piping Rock offers its Piping Rock 6-Bottle Essential Oil Starter Kit
for shipping. That's tied with last week's mention, $7 off list, and the lowest total price we could find. It includes frankincense, eucalyptus, peppermint, lavender, tea tree, and cedarwood oils, each in a 15mL bottle with dropper top.
Of note, coupon code "NEWSAVE10" drops it to $14.99 for new customers.
