Our discount system applies once you have purchased 3 or more items.
Your THIRD purchase triggers a discount  of £2 for all items.
There is no limit to the amount of discount nor to the value of the items.
Eg:- 1st item   £4.99  No Discount
         2nd item  £9.99 No Discount
         3rd item   £6.99  £2 Discount on every item in Basket
         
So on 3 items there would be a £6 Discount
