As with all auction titles and listings, don't always take these acronyms at
face value especially if there's no picture to back up the title's claims,
if in doubt contact the seller and ask about the condition of the
alt.marketing.online.ebay (this Usenet group).
Final Value Fee. This is the fee eBay charges as a percentage of the final
bid at the end of a successful auction. If nobody bids or the reserve isn't
met on a reserve auction, there's no FVF to pay. If the winning bidder backs
out for any reason, the seller can reclaim the FVF from eBay as the
transaction is not deemed successful. To do so, the seller must file a NPB
alert and wait 10 days, except when the winning bidder is NARU'd. For more
information, refer to http://pages.ebay.com/help/community/npb.html.
Not a Registered User. The user in question is not currently able to sell or
bid on eBay. This situation may be temporary or permanent. It may also occur
at the user's request. Generally speaking, most NARU'd accounts have
violated some policy or have an outstanding bill with eBay. Unless the user
has really bad feedback it can be difficult to guess why a user is NARU'd as
eBay doesn't state any reason why. For more information, refer to
Non-paying Bidder. Also refers to the Non-Paying Bidder Alert form. In other
words, the bidder of an auction hasn't paid, so you file a NPB alert to
provide a little push to help convince them to pay for your auction. It's
also the first step to reclaiming the FVF that eBay billed you. NPB alerts
don't go down as a black mark on the bidder's history, but FVF's do (unless
the FVF reason was that you both agreed to mutually cancel the transaction).
For more information, refer to
No Reserve. This short acronym is often found in auction titles to indicate
items offered with no reserve.
EBay's End of Auction Notice or alternately, your own End of Auction Notice.
EBay's Buy It Now feature. When a buyer uses BIN, the auction is immediately
ended with the bidder as the winner at the specified BIN price. BIN prices
are only present if the auction has no bids or, in the case of reserve
auctions, the reserve has not been met.
Verified Rights Owner. EBay gives the VeRO special privileges in determining
if auctions listed by other seller's violate their intellectual property
rights. If a VeRO member decides someone has violated their rights, they can
unilaterally cancel the auctions of other sellers.
All you need to do to join eBay's VeRO program is register an account,
create an About Me page describing your rights, and then register with eBay
as the owner of whatever intellectual property you are claiming.
