I wanted to try Acquarella nail polishes (they're water based), so after some research i find a seller on amazon uk that sells them for a decent price and reasonable shipping prices. I leave a review, and a few days ago i receive a mail saying my review has been selected and as winner of this month i receive an Ecotools eye brush set. I always complain how i never get to win at competitions like this, so i was truly surprised and happy.
