These are £9 -£11 in the supermarkets, so a decent saving I thought. My cat likes whiskas anyway :)
Tesco, Asda, Ocado -£9
Sainsbury's, Morrisons -£11
* also, don't forget the always available Farmfoods coupons. Another 10%, if you're doing a 'big shop'
if you don't get a voucher sheet through the post anymore you can register on line and they will send the vouchers to you via email. The expiry dates will keep updating and you can print them off anytime
