hello.
Just an observation. I have just looked at the items for sale and see some to be very old. plus some have dollar signs next to it. I am not being funny but dont you think an expiry date would be a good idea.. say 30 days from inserting the ad and/or a courtesy email from the seller to tell the admin dept advising that the item has been sold and they can remove it from the listings. Or just delete anything thats over 30 days. I would save space and time trawling through all the old ads.
I can do it if you are busy. run a shop so its easy.
