I don't sell at ebay , in fact i wish to . Nut i am just so busy and seem my schedule is full all the time . There is a ebay guide dvd given free in the net , but so sad is not shipping to my country . only US and Canada .

Yes, selling so many products at once is not easy at ebay.
If you don't have a good tracking system, you will be easyly lost track.
I introduce you using excel, from my blog you can see that how i use it to manage my online business.

I actually use Excel for a number of things, keeping track of my Ebay auctions just happens to be one of them. It's a great program.

Excel is easy to use and familiar to everyone i guess. You can formulate the calculation need that suit you.
You even can make a graphic or chart to see how's your online business growth.

I haven't actually tried to make a chart with it yet. Maybe I need to play around with it a little more

Excel is a very good tool for all financial needs. Charting is a very big boon to it.
Just get round the things and a lot of new ideas will emerge from Excel.

So how does one sell anything at eBay? Are there sites that explain that? It would be nice to sell off some of my unused belongings at my house...

spheric...ebay itself has tutorials on their site.

I wanted to get back into selling items on ebay myself. I stopped because of the shipping situation, It got kind of overwhelming. I made decent money on the things I had around the house, but I didnt know how much to charge for shipping and I think I lost out on money because of it (especially bigger items). I figured I better do more research and learn about pricing for shipping before I started back up.

Here's a good software.
