Hi! This didn't seem like a good question for Customer service, so I'm posting it here.
I like the Twinset deal, and would like to get one for a friend (and maybe another for myself!). Although the 6ml tank is more 'generous' offer, I like the 3.5ml tank. Is it possible to order the Twinset that way? If the cost would be slightly lower too, great, but would like that option.
thanks for responding when you can! Lisa
