Two things go wrong in this category, and both are settled before the show rather than after.
Not measuring
Height, width, depth in centimetres, and seat height for anything you sit on. Scale in a photograph is unreliable and this is the category where buyers find that out on arrival.
Deciding delivery afterwards
A wardrobe is not a parcel. Courier, your own delivery or collection — decide, say it in the listing, and remember collection is agreed before bidding. How pickup works.
Calling veneer solid
A real difference in value and in how a piece can be repaired. Veneer is not a fault; the word is.
Not showing the surfaces that get used
The top under raking light, the edges, the feet, the drawers worked on camera.
Refinishing an old piece
On anything with age, it usually subtracts. Common mistakes selling antiques covers why.
Posting a mirror or a framed piece
Glass that breaks damages what it was protecting. Offer collection.
Not bagging and labelling fixings
A dismantled wardrobe with loose screws in the bottom of the box is remembered for years.
The one that costs most
Quoting delivery before weighing. Heavy items cost real money to send and the difference comes off your own balance. How delivery is charged.
Questions people ask
Is collection-only a disadvantage?
A smaller room, and often the honest answer.
Should I repair before selling?
Describe rather than repair, unless it is small, cheap and you can say what you did.
Do plants post?
Many couriers will not carry them. Collection is usually better.
