The True Cost of Selling

Before listing anything, consider:

  • Time spent photographing and listing items

  • Storage space while waiting for sale

  • Effort handling buyer enquiries

  • Packaging and posting costs

  • Platform fees and payment processing

  • Failed sales and relisting time

Quick Value Assessment Checklist

High Potential for Selling

  • Brand name items in good condition

  • Current electronics (less than 3 years old)

  • Vintage or collectible items

  • Designer clothing with labels intact

  • Complete sets of items

  • Current trendy items

Better for Donation

  • Generic household items

  • Outdated electronics

  • Well-worn clothing

  • Incomplete sets

  • Items needing repair

  • Mass-produced decorative items

Where to Research Value

  • Check completed sales on eBay

  • Browse local Facebook Marketplace

  • Compare Vinted listings

  • Consult specialist dealers for antiques

  • Search Gumtree for similar items

  • Check CeX for electronics

The £20 Rule

A practical rule I share with clients:

  • If an item will sell for less than £20, consider if the time investment is worthwhile

  • Exception: If you can batch sell similar items together

  • Consider the seasonal timing of sales

The Final Decision

Ask yourself:

  • Am I willing to handle the entire selling process?

  • Would donating bring more immediate satisfaction?

  • Could someone benefit from this item more than I would from the money?
