Pick your items, your prices and your platform
It’s good to have a realistic idea of how much money you can expect to get in return for your sales. Old clothes might go for pennies, while a rare video game could fetch £50, and a nice old bike or violin may achieve a much higher price. Check sold prices on a popular site such as eBay (you can filter for sold listings via the site’s advanced search settings); this will give you a clearer picture of eventual sales.
Once you’ve decided on your products, choose the place where you want to sell it. Gumtree is good for getting rid of big, bulky items which buyers will most likely have to collect, as it encourages buyers to search locally; eBay is better for reaching a wide, specialist audience; Depop is pretty much made for clothes-mad teens; and if you’ve got a bunch of books to get rid of, and you’re not too worried about the price, Ziffit could be the place for you. Remember, a lot of platforms have age restrictions, so you may want to check these out before you list (we’ve detailed these below). If none of these work, there’s always Freecycle.
Many online resale platforms encourage well-written, detailed descriptions. Gumtree actually has a 12-word minimum for its listings; eBay encourages users to write in full sentences, with correct spelling, listing an item’s key points, as well as exactly what’s included in the sale. Other services, such as Depop, place less emphasis on words and more on pictures. If your kids are old enough to compose full sentences, why not encourage them to type out this bit? You can always correct them before you make it live.
