I am not sure if this is a question or venting; however, I can tell you that I have been selling on auction sites for 8 years. When I started to sell, I sold on Yahoo Auctions. I have stopped selling on Ebay, because it is no longer beneficial for me. On the contrary, I still buy things on ebay if the shipping fees are fair.
3 things have happened that have slowed down sells for some people: postage increase and fraud and frequent fee increases for sellers.
Yes, some people will say that it is about your wording, but after so long, you learn the trick of keywords. Some people will say it has something to do with your feedback numbers, but some people don't even look at feedback numbers.
I can tell you one thing that has saved me alot of wasted money of fees: research. Prior to listing an item, research Ebay and other sites to see if what you are offering is marketable. If there is a bunch of competition for the item that you are selling, you won't make much, because other people are selling the same thing for either a lower price or for free shipping.
High shipping fees can be a turn off as well. But, the biggest turn off for me was paying that big bill every month; I felt like Ebay was starting to pimp me.
It may be more cost effective to sell on craigslist, but you are getting a whole different calliber of people who shop on the each site.
A great photo is worth more than many words. I have found that I will not buy from people who have alot of junk in the background and blurry pictures. Also, I tried to give my customers more than one shot of a photo. Incidentally, if you want to list a bunch of photos, making your chances better to sell, you can use a picture hosting site, and not pay ebay for listing more than one photo.
If you questions about ebay, their community forum is very helpful. You can use that forum to help you with everything from the best camera suggestions to pricing.
Suggestion: If your items are worth more to you than $1.00, sell them for a fixed price, because people like me or just waiting until the last few seconds to bid $1.05 on your item, and then brag about how I bought this cellphone for $1.05 (just kidding).
