www.petplanet.co.uk currently have JWB 2kg bags on '3 for 2'. They were pretty cheap to begin with at £11.22 so you get three 2kg sacks for £22.44 which works out at £7.48 a bag. P&P is free when you spend over £29, they also sell Frontline, Drontal, Oko plus, Feliway, Dreamies plus loads of other things so very easy to make the order up to £29! I've been ordering Riley's RC sensitivity from them for a few months now and can't fault them for service and price
Pets at Home also have JWB on 3 for 2 (£13.78 each) so works out to £9.19 a bag - this is instore and online.
