Is It Cheaper to Ship with USPS or UPS?
Quick Answer
USPS tends to be cheaper for smaller, lightweight packages, especially when using First-Class Mail or Flat Rate services. UPS is often more cost-effective for larger, heavier shipments—especially if you need faster delivery or have access to negotiated rates. Ship Pros helps businesses analyze these factors and find the optimal shipping solution.
