Keep track of what you pay for groceries (or practically anything you buy on a regular basis), so you can determine the best price and best time to buy for each item. This spreadsheet allows you to input lists of categories for use in drop-down menus. Also, when you click on Category, it automatically inserts the current date, which is a big help when you input a whole grocery receipt. Feel free to delete the Sample sheet when you learn how to use it.
