The closest thing to a sample they have sent since January (actually, looking at previous boxes, in *any* of them, but I've only received the Jan-Apr boxes, so those are the only ones I can personally verify) was the lip scrub in March, and even that's not a sample. It's just a tiny jar (you barely need any, so the size is appropriate for the product. It's about the diameter of a nickel and, oh, maybe half an inch tall), and that's the size they actually sell (and the price is appropriate for the size: two bucks!).
Quality: Great! The only thing I have really been disappointed in has been one gel liner (Chancy, the shimmery purple), and I think it's actually user error since it's the first shimmery gel liner I've tried to use as liner (I use the Princess Diaries gel liner from the February box in a completely different way than this one should be used, and it seems to be a completely different consistency, too). I definitely need more practice with it because I'm still not quite sure about the best way to apply it. I'm very scared of the day they launch their new and improved swatches because I know my wishlist will just *balloon* as soon as I see all of the pretty colors.
(I have to confess that one added touch shows me just how much thought goes into the whole subscription package: Even the box itself is coordinated to go with that month's selections. February's pinkapalooza was in a pink box with purple metallic elastic holding it closed. January with the metallic green liner and green bracelet went out in a green box. April's neutrals had a blue bottom and brown lid, like the earth and sky turned upside down. I forget the colors of the bands holding those other three months' boxes closed, but I do remember that they matched. I'm looking forward to seeing the May box almost as much as seeing what's *in* the May box!)
