AABCDSThanks, turns out we were missing two drop tiers on the listing before it went live. They're in there now.
If anyone wants to order more than one color, "checkout" for 2 bottles, then email support@massdrop.com and they'll add a note to your file with the colors that you would like.
Well, you can buy the deep cerulean blue from Amazon for less than $30.37, the total price here.
