Not for the 5%: that comes off every order automatically. For the higher tiers, enter BF10 (orders of £100 or more), BF15 (£150 or more) or BF20 (£200 or more) in the coupon box at the basket or checkout.
No. One discount applies per order. A code replaces the automatic 5%, and the rate applies to the whole basket: a £160 order with BF15 gets 15% off everything.
Tiers are based on your basket total for products, before delivery is added.
