As we sell wine, we want to promote buying in multiples of 6 (this decreases the risk of stuff breaking in the box). However, it is also possible for customers to order individual bottles. With the current set-up, it is not really clear that you can also order individual bottles. We think by adding a dropdown menu this can be clarified (or maybe you have a better suggestion 
). I was thinking of doing the dropdown going 1-2-3-4-5-6-12-18-24-30, if it is possible that you don’t need to scroll down it would be perfect. Thanks for helping me!
