I haven't sold on ebay in years, have mainly been using gumtree/fb marketplace.
But some of my items aren't selling, so thought might be time to give ebay a go.
I had a look at the fees however, its 10.9% of the final price (including postage), plus paypal will take 2-3%…
I guess that's the way it is these days with the high fees, or do people have any ways around it such as this one:

I believe you could import a listing from Gumtree to eBay and not pay any fee. However, it is limited to 2 listings a month.
