If you realised you made a mistake and want to cancel your order, please contact us. Since we despatch quickly it may not be possible to stop your order so please follow the instructions for Returning a Product in those instances. Exchanges work in the same way. It will be faster to re-order a product rather than send it back for an exchange, so please follow the above instructions while you order the product you would like instead. We realise this means two transactions on your credit card but feel it is faster for you to get the product you would like.
