theBalm is having a half-off-everything sale on Tuesday from 10am to 12pm (noon) PST. They do nice matte eyeshadow palettes and blushers, I think, but that's just based off seeing them on other people. Maybe other GTers will have actual personal recommendations to share in the comments? Anyway, other times I've tried to buy things during online flash sales I've had issues with what I wanted selling out and the website freezing up, so if you want anything I'd choose it over the weekend and then buy it early in the two-hour window.
Also, I know I said I'd have that makeup sub-blog set up by now but I ran into technical difficulties, sorry. It should be done by tomorrow night, for real this time.
ETA: btw, they do ship internationally, but they charge $20 to Canada and $25 everywhere else. So, like, potentially worth it if you're buying quite a bit of stuff at sale prices but still very irritating.
