ok, i know referrals aren't allowed, however referrals aren't needed for this because you can just enter any email address and refer yourself many times until you unlock all codes. unlock first for a travel bottle, then a single cube, and then 3 sets of cubes. several to choose from.
Each level unlocks a single use promo code to purchase on amazon.
I did this myself 2 days ago and products arrived today. This ends in 35 minutes so you better hurry. I would say about 10 min to unlock all codes on your own. Less if your spouse helps...
