RTX 3090 used price guide and live deals
A RTX 3090 asking price is only comparable to another 2020 RTX 3090 with the same capacity and condition. This page tells you what to line up. The prices themselves come from the live search, not from a table. The RTX 3090, not the RTX 3090 Ti. Both say 24GB, and they are different cards. It is also not a 4090. eBay is the main shipped market. Facebook Marketplace and OfferUp work when you can see the card power on. Mercari appears when a seller will ship a boxed card. Swappa does not review graphics cards. If you opened this from a YouTube video, the price in that video is the creator's example, not a live comp.

Condition checklist
Run this list on a RTX 3090 before you treat two live asking prices as the same product. A parts listing is not a comp for a working one.
- 3090, not 3090 Ti and not 4090. Memory size alone does not identify it.
- 24GB GDDR6X on a 384-bit bus.
- NVLink fingers are a 3090 feature to confirm in photos, not a price.
- Working fans, an honest mining history, and the return window.

Local pickup versus shipped for the RTX 3090
Local cash on Facebook Marketplace, OfferUp, and Craigslist can skip a selling fee and a shipping label. A shipped RTX 3090 on eBay or Mercari adds that site's fee and the carrier. eBay is the main shipped market. Facebook Marketplace and OfferUp work when you can see the card power on. Mercari appears when a seller will ship a boxed card. Swappa does not review graphics cards. The search on this page is BuyLow's live search for "RTX 3090". It is not a map of one city.
eBay, Mercari, and Swappa for the RTX 3090
eBay: About 13–15% final value fee on most categories plus a small per-order fee; lower for some electronics. Mercari: A selling fee of about 10% plus card processing; check the current rate. Facebook Marketplace: Free for local pickup; shipped orders pay a percentage selling fee. Swappa reviews phones, computers, tablets, watches, and consoles. Do not expect a RTX 3090 listing there. A small flat-style fee; listings are reviewed and IMEI/serial checked. Compare only listings that match 24GB GA102 and 24GB GDDR6X.
Flip checklist for a RTX 3090
A flip is a real buy price, minus fees and shipping, minus a real sell price. This page does not have those two prices, so it does not print a margin. Confirm 24GB GA102 before you buy something to resell. Quote is only for an item you already own, and only when a buyback source has published a price.
- Match the spec on the device or the packaging, not only in the title.
- Subtract the fee notes above and shipping before you treat a gap as money.
- Local pickup can skip shipping. Meet in public and confirm it works.
- A number in a video is that creator's example. Search live listings.
