I know this sounds ridiculous but I am a student and as my savings dwindle I get more insecure.
So I am having a store cupboard spend up on asda onlone 
I love bulk buying beans and rice when I feel like this.
I'm even eating a bowl of porridge while I do it ... that I bought last time I did this but haven't opened 
It's also quite nice looking at each section closely, I cant be arsed to do that down every isle in the store.
