I'm going to try to find the 8-pan palettes today at my local Walgreens - my local WalMart doesn't carry WnW unfortunately.......I bought Silent Treatment and I'm Getting Sunburned. You really cannot beat the quality of these shadows for the price, and I agree with NouveauCheap that ST is a must-have for the taupe color!!!
Update: I did not find the 8-pan palettes yet, but there is a new merchandizing unit on the wall at Walgreens with slots for the 3 new palettes. They had all of the new 3-pan sets, so the good news is these are part of the regular line.
