After managing hundreds of brands on Amazon, we’ve noticed a pattern in how operators think about channel expansion: everyone debates Walmart, TikTok Shop, and international marketplaces, while Best Buy Marketplace — a channel with roughly 1,100 total sellers — barely comes up. That’s a mistake, and the window it creates won’t stay open.
Best Buy relaunched its U.S. third-party marketplace in August 2025 on Mirakl, the enterprise platform behind 450+ retailer marketplaces. By Q3 FY26 it had passed 1,000 sellers and grown SKU count 11x. Best Buy posted its best comparable sales growth in four years (+2.7%) that same quarter, and leadership has named the marketplace a core growth priority. Translation for operators: the retailer is motivated, the assortment is still being built, and the seller pool is measured in hundreds — not millions.
Here’s how to evaluate it properly.
The Curation Is the Product
The single most important thing to understand about selling on Best Buy Marketplace: it is curated, not open. You apply, Best Buy vets you against its brand standards, and most applicants don’t get in. Approval typically takes 1–4 weeks, and Mirakl reports an average of 23 days from application to first sale for approved sellers.
Amazon operators tend to read “application and vetting” as friction. Read it as economics instead. On Amazon you compete against millions of sellers, with ad-auction CPCs priced accordingly and a dozen lookalikes cloning any listing that works. On Best Buy Marketplace, your category might contain a handful of credible competitors. The vetting that slows you down at the door is the same mechanism that keeps the aisle uncrowded after you’re in.
We’ve said this about Faire and Target Plus, and it applies here with more force because the channel is younger: on a curated marketplace, the moat is the door. Every quarter you wait, more of your category’s shelf gets claimed by whoever applied before you.
It’s Not Just Electronics Anymore
The reflexive objection — “we’re not an electronics brand” — is increasingly wrong. Best Buy has expanded marketplace categories well beyond its core: kitchen and cookware, home and office, outdoor and seasonal, automotive tech, gaming furniture and accessories, musical instruments, toys and games, licensed sports merchandise, floor care.
The filter isn’t “is this a gadget.” It’s whether your product fits a tech-forward, higher-intent shopper who already trusts Best Buy with considered purchases. A $250 espresso machine, a smart pet feeder, a garage storage system, a massage gun — these fit. A $9 commodity phone case does not, and the vetting team will tell you so.
Best Buy brings roughly 200 million customers and reach into more than 70% of U.S. adults. That’s not Amazon’s firehose, but it’s a qualified audience with electronics-grade average order values — and marketplace listings sit alongside first-party product with customer review quality that Best Buy reports is on par with its own assortment.
The Fee Math (and Where to Verify It)
Fee structure, stated plainly, because sticker comparisons against Amazon mislead in both directions:
- Category commissions are set per category and disclosed inside the Marketplace Portal once you apply — the portal rates are the binding ones. Budget mentally for referral-fee territory comparable to other major marketplaces and confirm your exact category before modeling.
- Platform tooling: the marketplace runs on Mirakl Connect. Depending on your sales volume and how many Mirakl-powered marketplaces you sell on, paid tiers run roughly $479–$1,599/month. Confirm what applies to your situation during onboarding rather than assuming the top tier — but put a real number in the model, not zero.
- No FBA equivalent: you fulfill orders yourself (more below), so your pick-pack-ship cost replaces fulfillment fees.
Now the part of the math Amazon operators consistently miss: customer acquisition cost. On Amazon, a launch means months of 60–80% ACOS buying rank. On Best Buy Marketplace, a thin seller pool means organic discovery does real work from day one, and the self-serve “My Ads” platform operates without millions of competitors bidding against you. A slightly worse commission line with a dramatically better advertising line is a trade most operators should take — the metric to model is contribution margin after all fees and ad spend, not the commission rate in isolation.
Fulfillment: You Ship It, They Take the Returns
Two operational facts shape the whole channel:
You handle fulfillment. There’s no Best Buy warehouse network for marketplace sellers. Orders route to you and you ship from your own warehouse or 3PL. If your inventory already sits in FBA, Amazon Multi-Channel Fulfillment can serve Best Buy orders from your existing pool — we covered the MCF math in our fulfillment-backbone post — just account for the unbranded-packaging requirements and MCF’s per-unit premium in your Best Buy pricing. Whatever route you choose, take the shipping SLAs seriously: a curated marketplace that vetted you on the way in will also remove you for missed handling times.
Returns walk into stores. Over 80% of Best Buy Marketplace returns happen at its 1,000+ physical locations, and marketplace return rates run below Best Buy’s own first-party rates. For sellers, this is quietly one of the best return experiences in ecommerce: the customer gets an instant in-person resolution (which protects your ratings), and you get a consolidated reverse-logistics flow instead of a thousand individual return labels. If you sell in a category where returns eat 3–5 points of margin on Amazon, model this difference — it’s real money.
Who Should Apply — and Who Shouldn’t
Apply if you check most of these boxes:
- Category fit: electronics-adjacent, smart home, premium kitchen, auto tech, gaming, fitness tech, or any considered purchase a Best Buy shopper would recognize
- Brand standards: real brand, real content, professional imagery — the vetting team is assembling a shelf, not filling one
- AOV above roughly $40–50, where seller-fulfilled shipping economics work
- Operational maturity: you can meet handling SLAs from your own 3PL or via MCF without heroics
- Amazon is working but concentrated: if one channel is 90%+ of revenue, this is one of the cheaper diversification bets available right now
Skip it (for now) if: you’re sub-$100K/month and still have obvious Amazon upside (fix the core engine first — same advice we gave on Shopify and Faire); your product is thin-margin commodity that can’t absorb commission plus self-fulfillment; or you can’t staff another channel’s operations without dropping balls on your primary one.
How to Actually Get Approved
Because this is a vetted marketplace, the application is the first merchandising test. What moves approval odds:
FAQ
Is Best Buy Marketplace invite-only?
No — it’s open application, but curated approval. Anyone can apply at BestBuy.com/Marketplace through the Mirakl Connect portal; Best Buy selects sellers and products that fit its standards. Expect 1–4 weeks for a decision.
Will selling on Best Buy cannibalize my Amazon sales?
Meaningfully, no — the risk isn’t demand cannibalization, it’s price-parity discipline. Keep pricing consistent across channels (Amazon’s fair-pricing systems watch external prices) and treat Best Buy as incremental reach to a shopper segment that starts considered-purchase journeys at Best Buy, not Amazon.
How does advertising work on Best Buy Marketplace?
Best Buy offers a self-serve ads platform (“My Ads”) for marketplace sellers. Budgets go dramatically further than on Amazon for one structural reason: you’re bidding against hundreds of sellers, not millions. Start small, watch contribution margin, and scale what works.
Do I need to fulfill orders myself?
Yes — there’s no Best Buy fulfillment service for marketplace sellers. Ship from your own warehouse, a 3PL, or Amazon MCF (mind the unbranded-box requirement). In-store return handling covers most of the reverse logistics.
Is it worth it at ~1,100 sellers, or is the channel too small?
The small seller count is the opportunity, not the objection. Best Buy is actively growing assortment (11x SKU growth since launch) with committed leadership backing. Early sellers on Walmart Marketplace in 2016–2018 built positions that late arrivals paid dearly to contest. The same land-grab dynamic is running now, at smaller scale, with a vetting process keeping most of your competition out.
—
The honest summary: Best Buy Marketplace won’t replace Amazon for anyone. But for brands with the right category fit, it’s one of the few remaining channels where being early still matters — modest incremental revenue today, a defensible shelf position in a curated channel tomorrow, and a genuine hedge against single-channel concentration.
