if your in surrey, or near a Squires garden centre(not sure how many they have), I got a a squires magazine, in there were vouchers, one for a free 5litre bag, and another for half price John Innes No.1 at £2.50 for 30 litres. They also have a voucher to get secateurs for £1 and another to get 2 airs of gloves for £1. Not bad for £4.50 in total
