We placed an advert on their website for our custom banner printing service, http://www.custom.uk.net/5-custom-banners for 30 days. The advert was to sell our custom printed products. We sell hundreds of these items every week via other popular sites and from our own website. We were hoping to appeal to a larger audience and chose gumtree. They currently have a TV advert running and thought is was a well known brand. The advert did not bring in any sales. Gumtree market themselves well for sellers but does very little to promote it's services to buyers. Ebay and amazon on the other hand market to both seller and buyers. I asked Gumtree for a partial refund and they declined. If you want to sell something, pay the extra and use ebay.
