Gumtree Idiots

[Europa Jon]

I've recently had to offload a large amount of household items. Local charity shops are too full to accept donations. Some stuff is now on Ebay. Other items that are hard or impossible to pack & post have been put on Gumtree. So far, I'm not impressed with the average prospective purchasers using the latter website. Seemingly, 9 out of 10 users can't click on the map link to see where we live. 8/10 can't compose a basic sentence in English: I had a new compressor for sale. One interested party sent me the message: 'wot it cum wiv'. I replied 'it cum wiv plug'. 7/10 ask if an item is still for sale, then when I reply 'yes', I hear no more. My asking prices are lower than comparative items, yet a few tw*ts text an offer of half the asking price. Some say they're coming to collect the items and don't show. They rarely reply when I politely ask if they've reconsidered. One just now wanted me to do a 100 mile round trip to deliver a wardrobe! Imagine if they changed their mind upon delivery!
Sadly I've resorted to sarcastic replies to some of these dreamers. The stress is getting to me.
What's the average Pistonheads reader's experience of Gumtree? Is Facebook Marketplace any worse?

Latest Gumtree item I sold last night was an electric cooker. In the listing, I specifically wrote that it needed a good clean in the main oven. A couple came to look at it. I wired it up temporarily so they could check it out. They looked around it and agreed to take it. Tonight the wife sent me a photo of the top of the oven with baked on dirt, saying they're not happy, and it needs a professional clean. WTF! Less than 24 hours earlier, they were happy to buy it from me!
Another guy tonight asked if a DAB radio I want £5 for could pick up DAB! And in spite of my location being shown on the map next to the items' photos, and the post code link to Google Maps, nine out of ten enquiries ask whereabouts we are, sometimes twice!
