I received my AD yesterday as well. It does look like the only differences in the ADs will be the brush and lipgloss. I too was thinking it's a bit odd to be getting bronzer again now (and in December), especially when a teeny amount goes a long way for me, so I may cancel the third drop. It's just stockpiling and I don't really like or use the powder compact so I'll never finish one, let alone three (eBay time!). I like the flat, round serum brush so wouldn't mind another for the bronzer, say.
I agree about the difficulty getting the foundation out. I've only used it a few times, much as I like it, because I have other foundation to use up. I bought a second bottle in a lighter colour because I found my TSV choice a bit dark so I mix them. With one bottle, it is easy to get the serum out but I really struggle with the other. I have to remember which is which in fact because too much comes out of one if I squeeze as hard as the other. I just thought, I could try pushing a compasses point down the tube to make the hole bigger? I'll do that today and let you know if it has helped, Breeze.
