Well, I've gotten a bunch there, but probably mostly from the MAC website, then I've ordered a lot from Nordstrom. Just like you, I found out Friday at my Dillard's that they didn't have the mini paints, so I've got them coming from MAC...will be here this next Wednesday! I've found some things at Dillard's, tho, that were sold out on the website.
Those palettes were a bunch of work, but once I got the hang of it, it was easier. I couldn't really stand there at the counter doing it for more than one of the 15-pans at a time, tho. It's so much easier having them like that than in a pile of the little pots in a basket in my dresser!
