Compare the same quantity
The shelf price tells you what you pay for a pack. The unit price helps you compare packs. Divide the final price by the net quantity, then express both options in the same unit. For example, compare both at a cost per 100 grams rather than one per gram and the other per kilogram.
Use the price you will actually pay
Account for delivery charges, minimum order requirements and coupons you can genuinely use. A conditional bank offer may not apply to your order. Compare the cost after relevant charges rather than treating every banner offer as part of your saving.
A bigger pack needs a realistic plan
Bulk buying can cost more if food expires or deteriorates before you finish it. Think about consumption, storage space and the remaining shelf life. For unfamiliar products, a smaller pack may be a better first purchase even when the unit price is higher.
Check the product, not just the brand
Different variants, ingredients and pack compositions can make apparently similar offers hard to compare. Read the quantity and product description carefully. Keep a short list of staples you regularly buy; knowing their usual final prices makes future comparisons simpler.
