First of all, ALWAYS follow the tried and true advice of making a shopping list and sticking to it. Furthermore, this tip only works if you have certain (bad) habits that you are having trouble shaking; namely the foolish practice of not bringing lunch to work. Be honest, how many times have you thought 'I'll skip lunch today', and ended up caving for a vending machine snack or a trip to Subway? If you can't relate, then this tip isn't for you.
Basically, having snacks on deck (I prefer off-brand chips in bulk, and some kind of sweet like an apple or candy) is worth it even if you rarely fall into this trap. #finance
