Tips for an accurate result
Compare like-for-like units — ounces to ounces, not ounces to grams — before trusting a price comparison.
Watch for shrinkflation — the same package size doesn't always hold the same quantity from one year to the next.
Bundle deals only save money if you'd have bought every item anyway — price out the pieces you actually need separately too.
For recurring purchases, compare the true cost per use, not just per unit — a cheaper item used twice as often can cost more overall.
