You can earn loyalty points on every order you place on this website. If you select to create an account at checkout, your loyalty points will be saved and you can use these to discount future orders online.
Each product page shows you how many loyalty points you can earn when you order that item. Essentially, for each £1 you spend, you earn 1 loyalty point and for every 1 point earned, 1p will be added to your loyalty point balance (this is the same as some of the UK's biggest loyalty point cards). So for example, if you spend £500, you'll earn 500 loyalty points which can be used to discount a future order by £5.00.
