All Rimmel products are 40% off at Coles in this week's catalogue.
Note that Rimmel is 1/2 price at Priceline and that ends today (Wed 19 July). So this deal is only good if you can't get to a Priceline today. :)
I haven't tried any of their products but the the Provocolips lip color and Oh my gloss! lip gloss seem to be very popular and well-rated.
