Part 1: Domestic Shipping (Within the U.S.)
Let’s first look at the three most popular U.S. carriers: USPS, UPS, and FedEx.

| Carrier | Service | Estimated Cost (Zone 5) | Delivery Time | Notes |
|---|---|---|---|---|
| USPS | Priority Mail (Weight-based) | $15.75 | 1–3 business days | Best for medium boxes |
| UPS | Ground | ~$13.60 | 1–5 business days | Good balance of cost/speed |
