I bought some of this recently and the colour was wrong so they sent a replacement and said to keep the one that was no good.
I now have a £40 bottle of foundation that is barely used (just 4 pumps when I tested it)- seems a shame to bin it, but I guess nobody is going to want an opened foundation.
It's shade 10 if you already know your shade and want it for postage only (I'd do Evri if you arrange). I promise I'm hygienic!
