Carrier comparison: USPS, UPS, FedEx
Each major US parcel carrier has its own strengths on the origin–destination corridor.
USPS: USPS's flat-rate boxes can be the cheapest option for dense, heavier items in the 5–20 lb range when they fit.
UPS: For B2B shipments on this corridor, UPS Ground is usually the safest combination of price and reliability.
FedEx: FedEx Home Delivery covers residential at competitive rates, particularly for mid-weight (10–25 lb) parcels.
Transit time and timing considerations
What L5 customers ship on this lane
Optimizing your costs on this corridor
Three things to look at when you're trying to drive cost down on this corridor:
- Volume rebates kick in fastest on mid-zone lanes — most carriers will negotiate at 1,000+ packages a month on a single corridor.
- Mid-zone lanes are where multi-carrier rate-shopping really shows up: differences between USPS, UPS, and FedEx can hit 25–40% on the same package.

Frequently asked questions
Can I get insurance on shipments going from San Antonio to St. Louis?

Use the L5 rate calculator for an official rate by service, weight and zone, or contact our team with your typical shipment profile (volume per week, average weight, dimensions). We'll send back an apples-to-apples comparison versus your current shipping setup within 24 hours.
How long does shipping from San Antonio to St. Louis typically take?
+
Standard ground service runs around 3–4 business days. Two-day and overnight options are available at premium rates if you need a guaranteed delivery date. Holiday periods and severe weather can add 1–2 days, so build in buffer for time-critical shipments.
What's the cheapest way to ship from San Antonio to St. Louis?
+
For parcels under 5 pounds, USPS Ground Advantage is usually the lowest cost. Above 10 pounds, UPS Ground or FedEx Ground tend to win. The exact answer depends on dimensions, residential vs. commercial delivery, and volume — which is why multi-carrier rate-shopping (rather than picking one carrier upfront) typically saves 20–30%.
