Anyone with a Wilkinson's near them needs to pay them a visit; they have a massive pet food sale on. Purina, Natural Balance, IAMS and HiLife dry food all under £1 a bag. Tinned food like Felix 6 tins for £2. Wagg Dog Food 2.5kg £1. Dreamies 3 packs for £2 (you won't find any cheese ones in the one near me they are his Lordships favourite).
They have also got litter etc reduced. I'd never thought of going there for pet stuffs before but will definately be going again.
