Mine was placed 4/7, 4/8 (when I found out I had more to spend), and 4/15 (when I plain out wanted to confuse my husband, hee).
When I made the 4/8 one I did mention that my druthers would be for them to ship with the 4/7. But I also knew that sometimes that is a hassle to keep everyone sorted out, so no big deal if they were separate.
Besides that, I am a slow tester- I can only manage to wear a scent a day without too much sensory overload. By the time I get done testing the ones that I got, the rest of the orders will be there either way. And after a long day of work, coming home to a mailed package of goodies is never a bad thing, no matter how many times it happens. (Just ask Amazon.com, they know me by name there)
