The Milani Amore Matte Lip Cremes are now available on the Milani website HERE (free shipping on orders $25+). If you have been having a hard time finding these in-store, well here you go (SWATCHES HERE). Also, I got excited for a moment when I didn't see "limited edition" in the title of the listing, but if you read the description above, you'll see that Milani does state that these are limited edition. So get them while you can!
Oh, and don't forget that the LE Rose Powder Blushes are also on the Milani site right now as well, in case you're planning a haul.
Thanks again, @missjae1908, for the excellent tip!
PS: The retail price in-store at the Walgreens locations in my area is also $8.99. This is probably Milani's suggested retail price for these lip colors, but please keep in mind that different regions often have different pricing when it comes to drugstores (which is why you may have seen these for less at the drugstores in your area).
