Yeah, that all makes sense actually don, pretty much just changing formats.
No surprise to hear that the PS didn't help in increasing sales. I don't think that has been the powerful marketing tool it used to be for quite some time now.
About the only time that will get you the sale these days is when you are head to head with a non-PS, pretty much evenly matched on what you are offering. I think most would still probably go with the PS in those cases, but apart from that most ebay shoppers are more influenced by factors such as price, despatch times and so on.
Never heard of it actually costing anyone in sales though lol, that's not a glowing endorsement of it at all lol.
I remember when I made PS on one of my old accounts when first starting out, felt good to achieve it at the time, but it did nothing to increase my sales. When I didn't maintain it, strangely enough it was almost a relief when I lost it lol.
It just made me re-focus my efforts on what got me to PS in the first place, and not think that was going to create sales for me.
