Prices include shipping and are refreshed daily. Availability changes without notice.

P321 covers more than one configuration. Ryobi uses it as a family number — sellers list both the bare tool and the kit with batteries under it, and the part number alone does not say which. The figures above span both, so the range is wider than for a single configuration. Check each listing's title for what is actually included.

Common questions about the Ryobi 18V ONE+ Nailer (P321)

How much is a used Ryobi 18V ONE+ Nailer (P321) worth?
The median asking price for a used Ryobi 18V ONE+ Nailer (P321) is $104.75, across 35 listings currently live on eBay. Most sit between $89 and $124.48. This is what sellers are asking today, and it is refreshed daily.
What is a fair price to pay for a used Ryobi 18V ONE+ Nailer (P321)?
Anything at or below $89 is cheap relative to the rest of the market — that is the 25th percentile of 35 live listings. Above $124.48 you are paying more than three quarters of sellers are asking. The middle half of the market runs $89 to $124.48. The cheapest listing right now is $79.98 delivered.
Are used Ryobi 18V ONE+ Nailer (P321) prices going up or down?
Steady. The median asking price for a used Ryobi 18V ONE+ Nailer (P321) was $110.84 on Oct 17, 2026 and $106.12 on Nov 14, 2026 — within 5%, across 34 live eBay listings.
How long do used Ryobi 18V ONE+ Nailer (P321) listings stay up on eBay?
Listings for a used Ryobi 18V ONE+ Nailer (P321) that have ended stayed live for a median of 5 days. A listing ending is not proof it sold — sellers also end listings unsold, and eBay relists some automatically.
Is it worth buying a Ryobi 18V ONE+ Nailer (P321) used instead of new?
A used Ryobi 18V ONE+ Nailer (P321) asks about 93% of what the same tool costs new on eBay — $104.75 used against the new median. That is a narrow gap, and at that margin buying new is often the better deal once you account for warranty and condition.
How much do used Ryobi 18V ONE+ Nailer (P321) prices vary?
Half of the 35 live listings sit within a $35 window, $89 to $124.48. The tightest $20 window holds 15 of 35, $80 to $95. 26 of 35 (74%) are asking under $120. These are asking prices across listings live on eBay, so the spread shows how much sellers disagree rather than how much the tool actually sells for.
What should I sell my used Ryobi 18V ONE+ Nailer (P321) for?
Price it around $104.75 to sit mid-market, or at or below $89 to undercut three quarters of the 35 listings you are competing with. $124.48 is the top of the normal range. These are asking prices rather than sold prices, so they tell you where to start rather than what you will get, and buyers compare delivered cost — price with shipping in mind.
How many used Ryobi 18V ONE+ Nailer (P321) are for sale right now?
35 listings for the Ryobi 18V ONE+ Nailer (P321) are live on eBay right now, ranging from $79.98 to $161.99. We verify each one names this exact part number and is the whole tool rather than a part or an accessory.
Does the Ryobi 18V ONE+ Nailer (P321) come with a battery?
It depends on the listing. P321 is a family number rather than a single product — Ryobi sells the bare tool and the kit under part numbers that both begin with it, and sellers routinely write just P321. The figures on this page cover both configurations, which is why the range is wider than for a single one. Check the individual listing title for what is included.
