On all of my listings I say ' please do not email to ask if this item is still available, if it is advertised on here it will be available' and what do I get? Emails all the time asking just that.
Today I had someone arrange to pick up a piece of furniture when I didn't hear from them they claimed they emailed me earlier (they didn't) to say they were not coming as it wouldn't fit in the car. She had no intentions of coming so why not say so!
Most of the replies are just 'timewasters' Drive me mad if it wasn't for the fact it's free and there's no commission like eBay I wouldn't bother, wished there was an alternative to both eBay and Gumtree
