Frequently Asked Questions

Q: How do I calculate unit price manually?

A: Divide the total price by the quantity. For example, if a 24-pack costs $7.99, the unit price is $7.99 ÷ 24 = $0.33 per item.

Q: Should I always buy the largest size for the best unit price?

A: Not necessarily. Consider storage space, expiration dates, usage rate, and upfront cost. The best unit price isn't always the best value if you can't use the product before it expires.

Q: How do I compare products with different units of measurement?

A: Convert all measurements to the same unit first. For example, convert pounds to ounces (1 lb = 16 oz) or liters to milliliters (1 L = 1000 mL) before comparing.

Q: Do unit prices include taxes and fees?

A: Unit prices typically don't include taxes, shipping, or other fees. For accurate comparison, you may want to calculate unit prices including all costs.

Q: How often do unit prices change?

A: Unit prices can change frequently due to sales, promotions, supplier costs, and market conditions. It's a good practice to recalculate unit prices regularly, especially for frequently purchased items.

Q: Should I consider other factors besides unit price when shopping?

A: Yes, consider product quality, brand reputation, expiration dates, storage requirements, and your actual usage needs. The lowest unit price isn't always the best value if the product goes to waste or doesn't meet your needs.
