A comparison between FoxFlame's current setup (3PL warehouse with labels purchased through ShipStation) and Amazon Multi-Channel Fulfillment (MCF) for Shopify orders. Covers per-order cost across the live catalog plus the service and operational trade-offs.
On single-unit Shopify orders at standard MCF rates, the current 3PL wins for most of the catalog. The exceptions, and the levers that could change the outcome, are detailed below.
Moving the full catalog to MCF would increase fulfillment cost by roughly $1.50 per order on average, and by $5.50 to $6.80 on the bulky 4-pack lanterns and torches. Only the lightweight flame bulb SKUs ship cheaper through MCF today. Two levers could flip this picture: MCF Preferred Pricing (up to 15% off) and multi-unit orders, both covered below. On service, MCF improves delivery speed and tracking but weakens the branded unboxing experience and carries a Q4 storage and capacity risk for a seasonal brand.
The comparison covers the costs that actually differ between the two routes. Costs that exist on both sides at similar levels are treated as a wash and excluded from the per-order figures.
Handling ($3.00 per order at the 3PL), packing materials ($0.05 to $2.88 per unit), and shipping (carrier label bought through ShipStation, $6.00 and up by size). MCF bundles all three into one pick-pack-ship fee, so the table below compares totals against totals.
Storage is paid either way: pallet storage at the 3PL, or monthly cubic-foot storage at Amazon. Return fees also exist on both sides at comparable levels. Both are excluded from per-order figures, with one seasonal exception flagged in the findings: Amazon's Q4 storage rates triple.
Running fulfillment through the 3PL requires a ShipStation subscription (currently $15 to $175+ per month depending on shipment volume) plus the team time to buy labels, manage carriers, and chase delivery exceptions. MCF eliminates the subscription and the label workflow entirely: orders flow from Shopify to Amazon automatically through the MCF app. This overhead sits outside the per-order table but belongs in the decision.
A common misconception: the FBA fee a product pays on Amazon.com orders is not the fee Amazon charges to ship that same product to a Shopify customer. MCF has its own, higher rate card.
Example: School House Lantern 1-Pack, fulfillment fee when sold on Amazon. Amazon subsidizes fulfillment on its own marketplace.
Same lantern shipped to a Shopify customer via MCF, standard speed, single-unit order, including the 3.5% fuel surcharge active since May 2026.
Amazon bills on whichever is greater: actual weight or the space a box occupies (dimensional weight). Lanterns are like birdcages: light, but boxy. Most of the FoxFlame catalog gets billed on box size, not scale weight. The 3PL's flat handling fee ignores this, which is a structural advantage for this catalog.
Single-unit Shopify order, MCF standard speed (3 business days). 3PL cost = $3.00 handling + packing materials + ShipStation carrier label. MCF includes the 3.5% fuel surcharge.

The flame bulb SKUs (under half a pound) cost $1.10 to $1.24 less per order through MCF. The 3PL's $3 handling plus ~$6 shipping floor is expensive for small, light items.
The 4-pack lanterns and torches fall into Amazon's Small Bulky tier and cost $5.53 to $6.81 more per order through MCF. These are the worst candidates in the catalog.
With the full 15% MCF Preferred Pricing discount, 14 of 24 SKUs become cheaper or equal through MCF. Eligibility should be confirmed in Seller Central before a final decision.
MCF per-unit fees drop steeply when an order has 2+ units (example: a 1 to 2 lb item costs $10.64 alone but $5.25 per unit in a 4-unit order). If Shopify carts often hold multiple items, the gap narrows.
Storage is a wash most of the year, but Amazon charges $0.78 per cubic foot January to September and $2.40 October to December, exactly when decorative lighting peaks. The 3PL's flat pallet rate does not spike.
Per-order handling ($3.00), packing materials, the carrier label workflow, and the ShipStation subscription ($15 to $175+ per month by volume). The first two are netted into the table; the subscription and labor savings come on top.
Cost is half the decision. The other half is what customers experience and what the team stops or starts managing.
For delivery speed and tracking, MCF is a clear upgrade, and customer service tickets should drop. The trade is brand control: plain or Amazon-branded boxes instead of a controlled unboxing, and a meaningful Q4 storage and capacity exposure for a brand that lives on Q4. That points away from a full migration and toward a hybrid: fast-moving, light, standard-size SKUs through MCF where it is both cheaper and faster, bulky and seasonal inventory at the 3PL where it is cheaper and safer.
Open the MCF Preferred Pricing page in Seller Central. A confirmed 15% discount flips most of the mid-weight catalog to MCF-favorable.
Pull actual Shopify units-per-order distribution and one or two months of 3PL and ShipStation invoices, then rerun this comparison on actuals rather than estimates.
Route the flame bulb SKUs through MCF now (cheaper and faster), keep lanterns and torches at the 3PL, and revisit after steps 1 and 2 and after observing the customer experience.
