Quick answer by package weight:
| Weight | Usually Cheapest | Why |
|---|---|---|
| Under 1 lb | USPS | Can't beat First Class / Ground Advantage prices |
| 1-3 lbs | USPS or FedEx SmartPost | Compare both - depends on the route |
| 3-10 lbs | UPS Ground | Competitive price + $100 free insurance |
| Over 10 lbs | UPS or FedEx Ground | Built for heavier packages |
| 2-Day | UPS 2nd Day Air or FedEx 2Day | Very close - compare |
| Overnight | UPS Next Day Air Saver or FedEx Standard Overnight | Compare - $5-15 difference between them |
USPS - best for lightweight
Cheapest for packages under 2 lbs. Delivers to PO boxes. Free home pickup. But rates climb fast above 5 lbs and there's no included insurance.
UPS - best for mid-weight
Competitive for 3-20 lb packages. Every Ground shipment includes $100 insurance free. Guaranteed delivery dates, not estimates.
FedEx - the hidden budget option
FedEx SmartPost is often the cheapest rate nobody knows about for 1-5 lb packages. Strong express network for overnight and 2-day.
