Reseller glossary

The words and abbreviations you'll see on eBay, Vinted and in reseller groups, explained in plain English. Where a rule comes from a law or a platform, we link to the official page.

A

Auction

A listing where buyers bid and the highest bid wins when the timer ends. Good for items where you're unsure of demand; for everyday items a fixed price is usually simpler.

See also: BIN (Buy It Now), Reserve price, Sniping

Authenticity Guarantee (eBay)

An eBay service where some items in certain categories, such as trainers, handbags and watches, are checked by independent authenticators before they reach the buyer. Which items qualify is set by eBay and can change.

See also: Counterfeit (replica, fake), Item verification (Vinted)

B

Best offer

Also called: make an offer

An option on a fixed-price listing that lets buyers suggest a lower price. You can accept, decline or counter, and on eBay you can set prices to accept or decline automatically.

See also: BIN (Buy It Now), Watchers

BIN (Buy It Now)

Also called: fixed price

A fixed-price listing: the buyer pays the price you set straight away, with no bidding.

See also: Auction, Best offer

BOLO

Also called: be on the lookout

Short for "be on the lookout". Resellers use it for items or brands worth grabbing when sourcing, usually shared in groups and videos. Treat any list as a hint, not a promise of profit.

See also: Sourcing, Comps (sold comps)

Bumping (Vinted Bump)

A paid Vinted feature that shows your items to more buyers for a few days. Some sellers also say "bump" for relisting or editing an item to refresh it.

See also: Promoted listings, Relisting

Bundle

Several items bought from the same seller in one order, often with a discount you set. On Vinted buyers can bundle items from your wardrobe; a bundle cover photo helps them see everything at once.

See also: Lot

Business seller

Also called: trader, private seller

Someone who buys items to resell, or makes items to sell, for profit. Private sellers are clearing out their own things. Business sellers have extra duties (consumer rights, product safety, tax) and must say they're a business on the platform.

See also: Vinted Pro, GPSR, Trading allowance

Buyer Protection fee (Vinted)

A fee Vinted charges the buyer on top of the item price, covering refunds if an order goes wrong. Private sellers normally receive the full item price. Check Vinted's help centre for the current terms in your country.

C

Car boot sale

A sale where people sell their own things from their car boot or a table, usually at weekends. A classic place to source stock cheaply, so check items closely before you pay.

See also: Sourcing, Charity shop

Charity shop

A shop selling donated second-hand goods to raise money for a charity. A common place to source clothes, books and homeware.

See also: Sourcing, Car boot sale

COGS (cost of goods sold)

Also called: cost price

What you paid for the items you sold. Taking it away from your sales, along with fees and postage, gives your real profit.

See also: ROI (return on investment), Margin (profit margin)

Comps (sold comps)

Also called: comparables

Similar items that have already sold, used to judge a fair price. Sold prices tell you more than asking prices, because anyone can ask any price.

See also: Sourcing, Sell-through rate

Counterfeit (replica, fake)

A copy made to look like a branded item. Selling fakes is banned on eBay and Vinted and against the law. If you can't confirm an item is genuine, don't list it as the brand.

See also: Authenticity Guarantee (eBay), Item verification (Vinted), Hallmark

Crosslisting

Listing the same item on more than one site, such as eBay and Vinted. When it sells on one, remove it from the others straight away so it can't sell twice.

See also: Inventory, SKU

D

DAC7

The EU rules that make online platforms report sellers' sales to tax authorities, once a seller makes 30 or more sales or €2,000 or more in a calendar year. Being reported doesn't by itself mean you owe tax.

Tax threshold checkerEuropean Commission: DAC7 ↗Official source, checked 1 November 2026

See also: Platform reporting (HMRC), Business seller

Deadstock

Old stock that was never sold or worn, often still with tags or in the box. In trainers it means unworn pairs; for resellers it can also mean your own stock that won't shift.

See also: NWT (new with tags), NIB / NWB (new in box)

Dispatch time (handling time)

How many working days you promise to take before posting an item after it's paid for. Set one you can always meet; late dispatch hurts your seller standing.

See also: Tracked postage, Top Rated Seller

Drop-off point (parcel shop)

Also called: ParcelShop, pick-up point

A shop or post office where you hand in a parcel with its label or QR code, instead of booking a collection. Each carrier has its own network.

See also: Parcel locker, Prepaid label

E

EUC (excellent used condition)

Used, but with no visible wear. Always back it up with photos and mention anything a buyer might notice.

See also: VGC (very good condition), NWOT (new without tags)

F

Favourites (likes)

Also called: hearts

Buyers saving an item to come back to. On Vinted you can send an offer to people who favourited an item; lots of favourites but no sale often means the price is a little high.

See also: Watchers, Best offer

Feedback

Also called: reviews, ratings

Ratings and comments buyers and sellers leave after an order. Good feedback builds trust, so describe items honestly and post them quickly.

See also: Top Rated Seller, SNAD (not as described)

Flat lay

A photo taken from above with the item laid flat on a plain surface. Popular for clothes because buyers can see the shape and any marks clearly.

See also: Pit to pit

See also: Reseller, Sourcing, ROI (return on investment)

FVF (final value fee)
