USPS/UPS Comparison Chart
All prices in this chart were based on a 12"x12"x8" package being delivered to 8 Zip Codes in different USPS Zones. Prices were based on 2-3 Day USPS Priority Mail and UPS 5-Day Ground, delivered to a residential address. While the method used may have some minor discrepencies (USPS & UPS zones seem to differ slightly) the purpose of this chart is to get a better sense of when to use both services
