One page on the web that I make sure to visit at regular intervals is the sale page at Pout. They drastically reduce their stuff by huge amounts, so as you can imagine, the good stuff goes quickly. In the past I've grabbed triple lipgloss sets for £10 (the glosses are usually £12 each) and right now one of the best bargains is the irresistibly names 'Easy Ethel's G-Spot', a set comprising of a pair of polka dot pants and a lip polish worth £10. Grab it now (size s/m only, unfortunately) for a bargain £6. And just wait until you see the gorgeous way they wrap everything!
