Marketplace price comparison
| Marketplace | Typical ask | Seller fee | You keep |
|---|---|---|---|
| Facebook MarketplaceLocal pickup is free to list. Shipped orders add a selling fee, so this column is the local cash price. | $424 | None on local | $424 |
| OfferUpLocal sales are free. A shipped sale adds a service fee on top of the price shown here. | $415 | None on local | $415 |
| eBayMost electronics pay about 13.25% final value fee plus a small per-order fee. Sellers usually ask more to cover it. | $472 | $63 | $409 |
| SwappaSwappa charges sellers a flat fee on many devices and checks the IMEI or serial before the sale. | $450 | $15 | $435 |
| MercariAbout a 10% selling fee, plus payment processing that is not in this fee column. | $459 | $46 | $413 |
| Back MarketRefurbished stock with a warranty usually asks more than a private sale. Seller commission is about 10%. | $498 | $50 | $448 |
| AmazonAmazon Renewed referral fees are often around 15% by category, and the asking price includes a warranty premium. | $507 | $76 | $431 |
| EtsyAbout a 6.5% transaction fee plus a small listing fee. Electronics inventory is thinner than vintage and handmade. Inventory for this kind of item is thin; treat the column as a fee-adjusted estimate. | $450 | $29 | $421 |
| VintedSellers pay no fee. Buyers pay a protection fee, so asking prices sit a bit under other shipped sites. Vinted is strongest for clothes, so electronics and furniture are a thin market here. | $406 | None on local | $406 |

BuyLow saves the search for “Sony a7 III Fair” and pings you when a matching listing shows up at or under your price. Guests keep the alert on this device. A free account keeps it with you.
Notify me when a cheaper listing dropsInspection checklist
- Ask for the shutter count, or read it with a free tool. A high count is wear you can price.
- Shoot a bright sky at a small aperture to spot sensor dust and scratches.
- Check the lens mount, the battery door, and the memory-card door for cracks.
- Confirm the battery and charger are genuine and included.
- Test autofocus, stabilization, and a short video clip. A dead stabilizer is an expensive repair.
Scams and defects to watch
- Shutter count and sensor damage do not show in a product photo.
- Grey-market bodies can be real and still have no US warranty. Ask.
- A lens sold as 'clean glass' needs a bright-sky test, not a window selfie.
- Skip sellers who will not show the serial plate.

Questions
How much is a used Sony a7 III?
For this fair configuration, marketplace asking prices in the table run from $406 to $507, with an average around $453. The private-party anchor behind the table is $437 (BuyBackTronics reference price on BuyLow's sheet). Storage and condition adjustments are applied on top of that anchor when this page is not the base spec.
What is a buy-low price for a Sony a7 III?
$374 is the notify target on this page: the cheapest typical ask in the table, then about 8% under that. Listings under that number are the ones worth opening first. Anything priced like the average ($453) is ordinary, not a deal.
How much do eBay and Mercari fees take if I flip a Sony a7 III?
At the eBay asking estimate of $472, the fee in this table is $63, leaving about $409. Mercari's row uses a 10% selling fee. If you buy at the buy-low target and resell on eBay, the planning margin is $35 before shipping and your time. A negative margin means the gap is too thin.
Is an instant buyback better than selling a Sony a7 III yourself?
The instant buyback figure on this page is $382 (Buyback ceiling on BuyLow's sheet). A local Facebook Marketplace sale is modeled around $424 with no seller fee. Selling it yourself wins when you can actually collect that higher price. Buyback wins when you want a label and no meetup.
What should I check before I pay for a Sony a7 III?
Ask for the shutter count, or read it with a free tool. A high count is wear you can price. Shutter count and sensor damage do not show in a product photo.
