Blimey it feels like I might have penned a lot of this guide!
Point 2 - 'Not used in a year then flog it' is a little OTT. Well unless you're going for a minimalist look.
Point 7 - I think this is as important as anything, it can really make the difference if there are a lot of items the same/similar to yours or even if there's just one other.
Point 12 - I amazed to see how many people still put up fuzzy and poorly lit photos and then wonder why they get no bids.
Point 13 - I have a style when it comes to pricing so my listings can stand out. I'm not going to give it away but it's simple if you think about.
Point 14 - IMO 7-9pm is a little limited, I've had some considerable success with listings ending after 10pm. If you are selling to the UK and US a 10 to 11pm end time catches a lot of people.
Sometimes it just depends on the night, definitely check those advance TV listings though!!
Point 15 - I barely sell anything of value in the summer when the schools are off. For 6 weeks, up to quarter of your potential buyers are away sunning themselves or whatever. Summer is a good time to work on your listings using Turbo Lister and build up your inventory.
Point 22 - Use Dropbox, so so easy to do from Windows Explorer (or whatever), Just use the public link and in Turbo Lister put in the HTML code
<img src="your link goes here">
Then you can move it around using the tools, or alternatively learn some more coding.
Point 29 - I use
http://www.seajays.org.uk/postage/ and a decent pair of kitchen scales. I also have cardboard Royal Mail letter size guide to avoid getting caught out, thinking something is a large letter and the Post Office say it's a packet and then you get hit with double the price.
Point 36 - Never found any worth selling books on eBay, not much on Green Metropolis either. Amazon really has the lock-down on this, best to sell there every time.
Point 37 - More unusual records and CDs sell well on eBay. I personally wouldn't touch Music Magpie, prefer Amazon in the main.
Point 40 - With some things, especially those that aren't selling, I do think you have to be realistic and consider giving them to a local charity. I have a great guy from Oxfam who collects just about anything!
