You are not doing anything wrong as far as your
listing. I've been on ebay since 1999 and in all this
time have not sold as many items that I thought
I would sell. Its cost me more to list than I've made.
Not to be negative, but ebay is so saurated that
getting any bids sometimes requires listing your items many
times. Also the item that your trying to sell is not in season
right now, so that could one reason.
I had as many as 20 to 30 items listed and each time I logged
into ebay to see if I got any bids, I was disapointed.
However if you have the money just keep listing eventually
you'll get some body looking for the item your selling.
Sorry,and I am sure this responce don't help you however I would
suggest U-bid, I'm having much more success
PS: I am now using ebay to find products to buy rather than selling.
PPS: Jimmy, has posted some good tips, you might want to look at
them. They are on this fourm as a sticky
PPPS: Ebay is a numbers game, The more you list the greater
chance you'll sell your items.
