Petsupermarket.co.uk are currently doing several types of Eukanuba dog food at £6.99 for 3kg instead of £13.99. This works out at £34.95 for 15kg against the normal price of £42.99 for a15kg bag. If you dont mind the smaller bags it's a good saving, plus if you spend over £100 there's a £15 voucher (psbig15) attached. Unfortunately they don't seem to be doing Quidco at the moment.
