Frequently asked questions

What fees should I expect when bidding on online auction platforms?

Most platforms charge a buyer's premium, which is a percentage added to your winning bid amount. Some sites also charge flat listing fees or administrative costs depending on the category.

How do I ensure an online auction item is authentic?

Stick to reputable platforms like Sotheby's or Bring a Trailer that vet sellers and provide expert authentication. For peer-to-peer sites like eBay, always check seller ratings and request certificates of authenticity for high-value items.

Can I return an item purchased through an online auction?

Return policies vary entirely by the platform and the individual seller. Traditional retail auction sites may offer returns for misrepresented items, whereas salvage yards and estate sales typically sell items strictly on an as-is basis.
