1. You'll never, ever, have to pay full price. Because of deals with suppliers and seasonal changes, grocery stores have sales cycles, which typically last between 6 and 12 weeks. That means products are at their lowest prices every month and a half to three months. A price book can help you predict when that will happen.
2. You'll know a good deal when you see it. Apples for $1 a pound sounds great, right? Not if you know that they were going for 50 cents last week. A price book lays out cost trends in black and white, so you can anticipate the best deals and won't be fooled by sales that aren't as amazing as they seem.
3. You'll know exactly where to shop. Of course, one store isn't always going to offer the best deals on every item on your grocery list. Keeping a price book lets you clearly see how vastly costs differ among retailers, and it serves as a guide to the places where you can get the deepest discounts.
