I'm eating some sandwiches and I've had to use some really shitty bread that my DH purchased and it's frankly ruining my lunch 
I'm more than happy to buy own shop brands but I really do believe that some things have to be the 'real thing' and I will not buy cheaper versions to try and get a better deal.
My list includes cereal, nice bread, tea bags, Nutella and pasta sauces 
What about every one else??
