Well you do have to spend a little but you can just choose the two cheapest options on the Superdrug page but at the time of writing that's 27p. Just buy 2 items and they'll give you a free 5ml Versace Bright Crystal perfume. I'm told it smells fantastic!
Versace introduce Bright Crystal - a precious jewel, a fresh, vibrant and floral fragrance, with delicate tastes of colourful and juicy pomegranate grains, lotus flowers and the enticing presence of plant amber, acajou and musk. A perfect scent for the Versace woman who is a hybrid of strength and confidence yet feminine, sensual and always glamorous.
