This offer has been knocking around a few forums for a while now, so I thought I'd post it here for all to see.
Beauty Counter Direct is an online cosmetics store which has issued a number of FREE gift codes, which you can receive by paying for the P&P only. The free gifts are limited to one per order and you do not have to purchase anything else, but I believe they are worth quite a bit more than you pay for the P&P. The P&P is £2.95 for each order.
Promotional Code: EAW2: Free Elizabeth Arden eyeshadow worth £12
Instructions: Click the "Go to deal" button to link to the eyeshadow, enter the promo code in your basket, then just pay for the P&P.
See the forum thread (comments) for the links to each free gift, and the codes to use. I have just used the Free eyeshadow code above, and the delivery was really fast! Paying £2.95 for a good quality eyeshadow was well worth it. I opted for the cocoa colour - it's very nice.
