One of my all time favourite concealers is MAC's Select Cover Up. It gives amazing coverage, creating a flawless finish to your skin, it is so good I live in hope that one day MAC will bring out a foundation version of it. That's how good it is.
So back to the original point of this post. I am NW20 in this concealer so a few months back I went down to my local MAC for this one specific item. The SA toddled off to collect my product, I paid, I left ... I got home and discovered the SA had in fact sold me NW15. Oh the frustration!
I ended up just using it despite how light it was but of course this meant I couldn't return it. A few weeks later I went back again to purchase the correct shade. Again, I asked for the product in NW20, I paid, I left ... I got home and discoved the SA had solde me NW25!!! What the actual heck?! 
Don't these girls listen? I swear MAC girls are the absolute worst in the customer service stakes, I never ever have a good MAC experience.
So what is a girl to do? Well ... I now custom blend my own concealer, of course. And it looks like the MAC girls may have done me a favour as not only can I mix these 2 concealers to create NW20, I can now lighten or darken it by adding a little less or a little more of each shade. Perfect for when I am wearing fake tan or looking a bit pasty.
In fact, this is working out so well for me I may continue to buy 2 different shades in future so that I can always blend ot the exact shade I require for my skintone. I even find that I'm using less product this way.
Funny thing is, I do this with foundation all the time, not sure why I had never thought about trying it with concealer.
So thanks to the MAC sales assistant for messing up my purchase twice, it has turned into quite a clever mistake!
