Discover how rising carrier costs are reshaping e-commerce shipping in 2025—and why Fifth Shelf’s locked-in Amazon Shipping rates give partner brands a critical competitive edge.

As of Q2 2025, USPS has implemented another increase in Ground Advantage rates, while FedEx continues to scale back regional services—especially in rural zones and select Western states. For e-commerce brands relying on traditional 3PLs, these changes create pricing pressure and fulfillment uncertainty—especially as 2025 shipping rate changes become a growing concern for every operator.
Key Takeaway
While competitors scramble to adjust to USPS price increases and FedEx's shrinking regional footprint, Fifth Shelf partners enjoy fixed, industry-low rates for the next 24 months through Amazon Shipping. The result? Competitive pricing, faster delivery, and scalable margins that win Buy Boxes.
Why 2025 Shipping Rate Changes Are Now the Margin Killer
Let’s look at a simple example:
A grocery product shipped in a 14x12x10 box weighing 6 lb costs Fifth Shelf ~$8 to deliver.
The Amazon FBA fee for the same box can hit $11.50+, depending on product tier and placement fees.³
Now scale that across 1,000 units: a $3.50+ per-unit difference turns into $3,500+ in avoidable costs.
For larger or heavier items, the gap gets brutal:
A 24x16x12 box at 20 lb costs us around $14.
Amazon FBA charges $18.94–$24.60 or more depending on the size tier and distance from regional DCs.³
Even small-but-heavy items suffer: 20 lb in a compact box still incurs oversized weight fees at FBA.

Smart Brands Are Ditching FBA for FBM
Some of Fifth Shelf’s most successful partners opt for FBM (Fulfilled by Merchant) instead of FBA to preserve profit and speed up restock flexibility. Why? Because:
We deliver 90% of packages in 1–3 days, thanks to bicoastal warehouses.
Even when delays happen, only 10% of packages rarely exceed 4–5 days—comparable to Amazon Prime reliability.
Fifth Shelf’s high-volume contracts with Amazon Shipping keep costs flat for 2 years, while everyone else’s go up.
