A few weeks ago I ordered this Butter London set for $9 with free shipping:
Here it is on the website, but it's apparently sold out. Almost all of these polishes are limited-edition - the only one that's not is Doily (which I keep wanting to call Dolly). I have swatches of all of these - I swatched them in pairs, and I'll go through those below, but here are all the bottles:
This is Doily and Hush Hush:
This is Password Please and Spotlight.
And last, we have Doily again because I swatched it again, this time over Looker, which is in the middle, and then also the last topcoat, which is Bubbly:
I'm not really sure if the ombre brush was necessary because this are pretty much just straightforward top-coats and I doubt that I'm really going to use it. But for $9, this is a deal any way you look at it.
