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

P400 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.

How long do used Ryobi 18V ONE+ Sander (P400) listings stay up on eBay?
Listings for a used Ryobi 18V ONE+ Sander (P400) that have ended stayed live for a median of 44 days. A listing ending is not proof it sold — sellers also end listings unsold, and eBay relists some automatically.
How much do used Ryobi 18V ONE+ Sander (P400) prices vary?
Half of the 14 live listings sit within a $11 window, $27.69 to $38.48. The tightest $5 window holds 5 of 14, $36 to $40. 8 of 14 (57%) are asking under $35. 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+ Sander (P400) for?
Price it around $34.42 to sit mid-market, or at or below $27.69 to undercut three quarters of the 14 listings you are competing with. $38.48 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.

14 listings for the Ryobi 18V ONE+ Sander (P400) are live on eBay right now, ranging from $24.03 to $47.43. 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+ Sander (P400) come with a battery?
It depends on the listing. P400 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 P400. 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.
