Smart Shopping Tips
Always Compare Unit Prices
Don't just look at the total price. Calculate the price per unit/weight/volume to find the real value.
Bulk Buying
Buying in bulk often saves money, but only if you'll use everything before it expires.
Watch for Sales
Combine unit price comparison with sales to maximize savings. Sometimes smaller packages on sale are better deals.
Track Prices
Keep track of prices over time to know when you're getting a good deal vs. when prices have increased.
Why Compare Unit Prices?
Comparing unit prices is one of the smartest shopping habits you can develop. While the total price might seem lower for one product, the price per unit might actually be higher. For example, a "family size" package might cost $10 for 500g ($20/kg), while a smaller package costs $3 for 200g ($15/kg) - making the smaller package the better deal per unit!
