Smart Shopping Tips
Unit Price Comparison
Always compare price per unit, not total price. A larger package isn't always cheaper per unit. Store brands often have the same quality at lower unit prices.
Bulk Buying Caution
Bulk is only a deal if you'll use it before it expires. Calculate the unit price and consider storage space, shelf life, and whether you'll actually consume it all.
Sale Price Reality
"Sale" doesn't always mean best value. Compare the sale unit price to regular unit prices of alternatives. Sometimes the regular price of a store brand beats the sale price of name brands.
