I'm a private seller with more than 400 items for sale on Ebay but with the recent introduction of Ebay's maximum 300 listings per month, this means only 300 get listed in any month. If I want to list more, I have to pay a £0.35 per listing extra charge.
My sales rate runs at about 5-10 items per month so you quite quickly realise that paying £0.35 per extra listing just doesn't make financial sense - getting the remaining 100 listings posted means £35.00 up front which would eat into monies made on sales of at least one third of that value.
Previous to this irritating novelty from Ebay, the listing maximum was well in excess of 400 and Ebay's charges only applied when a sale was made. This was clearly better as everything I had listed was visible to buyers, whereas now 25% of my listings remain invisible to buyers.
Not best pleased.
