Thank you for your question. There are two ways of doing this. One is to highlight each fragrance one by one in the drop down list and click "Add to Cart" (if you want more than one of a fragrance, type the number of bottles you want in the quantity box before adding to the cart) and repeat the process to add more fragrances.
The second way is to select the first option in the drop down list "NUMBERS TYPED IN COMMENTS BOX" as the fragrance, update the quantity to the total number of bottles you are getting and click "Add to Cart". Then during check out, you will type the fragrance names and numbers for each fragrance in the comments box. The fragrance numbers can be found on the Printable Fragrance List page: https://www.perfumeoildirect.com/Printable-Fragrance-List_ep_41.html.
