Instructions:OK - as Abel and Cole put it - this is simple but there are some hoops to jump through...for £50 free shopping, you might expect there would be!
Here they are:
1) you have to order 4 separate weekly deliveries including a fruit and veg box set up as "every week" delivery, the first one of these needs to be delivered before 9th April.
2) Each delivery must be over £15 + 99p delivery. Quote the code at the checkout
3) Money will be credited to your accoun t the day before your 5th order is delivered and can be spent on anything at all, but must be used by May 21st.
Not too hard :)
