Running out of your favourite products is a really horrible experience, but running out of high end products that you once got as a treat for yourself is something I don´t want anyone to experience (okay I´m being a little dramatic here). Anyway hitting pan or emptying your favourite products calls for starting the hunt for the ultimate similar that will hopefully be just as good as the "original" or is even better, but just for a fraction of the price.
I collected 3 products that I (nearly) ran out of and think I found quite good similars of (I upgraded on one product but you´ll see in a minute).
