For five years Amazon sat behind your other channels. It stored the units, shipped the Walmart order, and left the workflow the moment a label printed.
Since last Thursday it sits in front of them.

What shipped on September 24
Amazon announced three things at Accelerate on the same morning.
A multichannel workspace inside Seller Central. Connect eBay, Shopify, TikTok and Walmart, link those listings to your Amazon catalog, and see every channel's unshipped orders on one screen — each one a click from being sent to Amazon to fulfill. Free, rolling out gradually to US sellers. Listing sync and a cross-channel profit view come later.
The Prime badge on your own site, at no added cost, for merchants who fulfill through Multi-Channel Fulfillment.
And a reworked MCF Preferred Pricing Program: 15 to 25 percent off fulfillment fees for the first six months. No contract.
Most coverage filed these as three stories. They are one.
The tool is free because the tool is not the product
The workspace earns Amazon nothing. What earns is the pipe behind it.
The workspace puts your Walmart order on the same screen as your Amazon order, one click from Amazon's network. The badge lifts conversion on your own site only for orders that ship from Amazon's network. The discount makes the first six months of that routing cheaper than whatever you use today.
See it, route it, ship it. Together they move your off-Amazon fulfillment into the building your Amazon business already lives in, priced to win volume through Q4.

What the 25% is made of
The saving combines two things: a discount on MCF fees, and FBA credits per unit shipped.
The first is money off. The second is money you can only spend inside Amazon's network. A credit on your FBA bill is worth face value only while you keep shipping through FBA at the volume that earns it.
Then the clock. Six months from an October enrollment ends around April. By then the Q4 volume has shipped, the 3PL contract you didn't renew has lapsed, and its inventory has gone into FBA. The rate that matters is not the one you enroll at. It is the list price you're on in April, with no second warehouse to walk back to.
None of that makes MCF a bad deal. For plenty of catalogs it wins at list. The question is whether it wins at list for yours.
The Numbers
September 24 — four rival channels connected to Seller Central in one announcement: eBay, Shopify, TikTok, Walmart. US only, gradual
15–25% — MCF fee savings for the first six months, combining a fee discount with FBA credits per unit shipped
40%+ — share of eligible own-site orders early adopters shipped with Prime delivery, per Amazon
95%+ — Amazon's independent sellers already selling on more than one channel, per Amazon
71% — Amazon-primary sellers active elsewhere who still earn three-quarters or more of marketplace revenue on Amazon (Marketplace Pulse Seller Index)
Translation: Amazon didn't build a dashboard. It built a route — from the screen where you see a Walmart order to the warehouse that ships it — and discounted the first six months of the trip. Take it if the route wins at list price. If it only wins at 25 percent off, the discount is the whole case, and a case with a six-month expiry isn't a fulfillment strategy. It's a Q4 promotion, and you're the customer.

The Brief
September 23 — Seller Central moved into a chat window. Amazon's new plugin connects Seller Assistant to Claude or Amazon's own Quick assistant: listings, inventory, sales and performance data, with each action approved one at a time. Beta in the US. The approval click now happens wherever your team chats — decide who is allowed to approve a price change before someone connects it for you.
Shopify already runs the same hub in reverse. Its Marketplace Connect manages Amazon, Walmart, eBay and Target Plus listings from inside Shopify. Two hubs now want to be the master copy of the same product. Pick one before both are syncing the same listing, or the last edit wins and nobody knows which system made it.
Prime Big Deal Days is October 6–7. What's left in your hands is stock. A deal that sells through on day one hands day two to whoever still has units — check weeks of cover on every deal ASIN before you touch a bid.
Quick Win
Delegate to whoever pays the 3PL invoice. Thirty minutes, before anyone clicks Enroll.
Open last month's 3PL invoice. Add pick, pack, packaging and outbound postage, then divide by orders shipped. For the order count, use the order or first-pick line, not the per-item pick line. If you buy your own labels, add that postage in.
Download Amazon's MCF rate card (supplychain.amazon.com, MCF pricing) and price your three highest-volume off-Amazon SKUs at standard speed, at list rate, not the discounted one. Fees are per unit and fall as units per order rise, so use your typical order size. Then add what the list rate leaves out. From October 15 to January 14, that's the holiday peak fee. Then add the 3.5% fuel and logistics surcharge on top of the total. If you're running this after October 15, add your 3PL's own peak surcharges too, so you're comparing peak against peak.
Subtract. 3PL cost per order minus MCF all-in per order, for each of the three
The artifact: three numbers, written next to the enrollment button. Positive — MCF wins at list, the discount is a bonus, route freely. Negative — the discount is the whole case, so route overflow only and keep the 3PL contract alive through April.
Storage isn't a wash. Units that move from the 3PL into FBA pay Amazon's October–December storage rate, roughly two and a half to three times the rest of the year — if the gap is thin, that's the line that erases it. The number also doesn't price the Prime badge: if it lifts own-site conversion, that's revenue, weighed separately. And whatever it says, don't cancel the 3PL in October on a rate that expires in spring.
The dashboard costs nothing.
The route it draws gets priced in April.
See you Friday.
