@Seagoon_ @melbourne So I stopped by Priceline while I was at the shops to pick up some foundation.
On my way home, I noticed that I got the one that's a shade darker than I normally get.
Then when I got home, I realised that I had made the exact same mistake last time.
The moral of the story? If you're going to be a careless idiot, it pays to at least be consistent.
