Carrier comparison: USPS, UPS, FedEx
Each major US parcel carrier has its own strengths on the origin–destination corridor.
USPS: USPS Ground Advantage is usually the lightweight winner — work-share access lets us inject parcels deep into the USPS network for additional savings.
UPS: UPS's daily pickup network is unmatched on volume lanes; rate stability is also a plus for budgeting.
FedEx: FedEx Express options on this lane are worth considering only for time-critical shipments — premium rates kick in fast.

Frequently asked questions
What's the cheapest way to ship from Boston 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%.
How long does shipping from Boston 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.
