Buy 3 of a single product and you automatically save 6% on those items at the checkout page. Buy 6 products and you save 9%. And if you really want to stock up and save big, buy 12 and save 12%.
And you do not have to limit yourself to one scent. For example, you can buy three bar soaps (lavender, verbena and apricot) and you still get the 6% discount. It's as easy as 1,2,3 or in this case 3,6,12.
