I know it is not a great food but if you enjoy them once in a while then go for it. All Rustlers products are on a half price offer @ Morrisons on 99P. Now if you follow the link then you can print out a coupon which will enable you to buy one get one free! Just fill in your details. So basically 2 burgers for 99p. I think there are about 4 or 5 varieties in my local morrisons. http://www.rustlersonline.com/thorpe_3.php
Even better if you buy them from Somerfields as they are 92p there! Thanks Doncrombie!
