So.. Burton are giving away vouchers codes between 15% and 60% off your order. The codes are not unique so its a hunt to find the highest ones. The codes don't stack and i haven't been able to get them to work with any other code.
Don't forget free click and collect (its not very quick but it is free) and of course 5% Quidco or TopCashback.
So far we have:
25% code - AT4EV97
20% code - SSHB26
Burton also take gift cards onsite, if your near a morrisons, buy gift cards for 2p off per litre of fuel and use them on site.
