* "Curse Your Sudden But Inevitable Betrayal" is a Firefly quote, for people who don't already know this. Here's a nice short video of that bit:
I bought Tiramisu about a year ago for $1, on clearance. I'm fairly sure these "Sephora Collection" minis aren't available any more, and I don't believe they've been replaced by other Sephora Collection polishes, either. (Oh, huh, there was a Rio neon collection earlier this year, which is now on clearance. I missed that completely til now. But that's the only polish on their website under the Sephora Collection name right now.)
All of the names in the 2015 Square Hue collections are street names. Each month it was a different city, and all of the ones I've checked on have turned out to be places where you shop. Via Sant'Andrea is in the Milan collection, and it seems to hold true, there, too, near as I can figure out.
