I've seen some at the counter that looked like the ones the bloggers received. And a couple of my friends ordered them online from Nordies and received a couple of messed up ones. It's not a big deal b/c they can be easily nudged into place, but I don't think it can be said that it was simply the samples they received. I think it's just the nature of the product.
I've mentioned it before, but MAC should have really included a plastic stopper like the ones L'Oreal includes w/ the Infallibles. It would prevent product from shifting around.
I agree, luckily all of mine arrived safely. I went to my local Mac store today to get Dynamo and Infra Violet I couldn't wait for them to stock them online.
