Free Avon Full Size Lipstick Just Pay Delivery @ Avon
Instructions: Enter KISSPOST at checkout. This will add a card to your basket. Then add Red Kiss - Moisture Seduction Lipstick Red Kiss to your basket and it should display as 'FREE'. You will also recieve a discount on your p&p. Standard delivery will cost £1.75.
There does not appear to be a minimum spend so if there's nothing else on the site you fancy you can just get the lipstick itself for the cost of £1.75 for p&p.
Alternatively, you can use code MVC10 instead for 10% off your whole order.
