If you had added a potpourri to your cart and then realize you want a dram of the corresponding scent, you will need to set the number of the potpourri to zero before clicking on the Order button for the dram bottle, otherwise you will end up adding the potpourri again.
However, each set of potpourri & dram is separate and previous counts do not need to be reset.
You may view your shopping basket or checkout from the buttons at the bottom of the page or continue shopping.
