All of the following are good budgeting strategies if you want to save money at the grocery store EXCEPT:
A. Focusing on unit price when comparing similar products
B. Building a weekly meal plan around items you already own or items that are on sale that week, rather than just choosing foods you'd like to eat
C. Focusing only on the price when comparing similar products
D. Preparing a grocery list before you go to the store and avoiding buying items that aren't on the list
