I decided to make my own pocket calendar after a fruitless search for one that I liked. I took a used mini-composition book and covered it with scrapbooking paper and packing tape. Then, I printed out mini calendars, cut them out, and glued them into the book.
Since then, I’ve also added a price book to my calendar book. I printed out mini spreadsheets that allow me to write store names, dates, prices, item sizes, and prices per unit, with one page per item. Every time I find a better price, either in a store or in a grocery ad, I write it in the price book. Now, when I see chicken breasts for $1.97 a pound, I can look in my price book and see that they went for $1.29 a pound last month. It really helps me to save money. (I got the price book idea from Family Feasts for $75 a Week, which was written by Mary at Owlhaven.)
