Yeah I know I’m no longer a student (got graduation soon yay!) but me n my gf go to Aldi when we’re on a tighter budget (Aldi is class tbh) n that’s usually a £40-50 shop to last us a couple weeks. Even when I stayed in halls in 1st year I was going to Lidl. So it sort of baffles me that OP is saying £260 is a tight budget especially when it’s just for food
