Can you tell me about ebay?

1)Can you tell me about all the implication I might face when I start selling in ebay?

2) Why I hear that ebay charge you for selling? true?
3) How many percentages does ebay take from me if I sell a item that cost 20? how much they take?

How can I understand this kind of thing?

there are basically no implicatins you face when you start selling on ebay as long as you sell with secure payments like credit card or pay pal...Ebay usually charges a really low fee of putting things up unless you want to add like additionals...i've even put things up for free when they had some promotions...and ebay barely takes a percentage of anything unless, again, you want to add additional pictures or features to your item

dont wory about it proably cost you 50 cents dosent mater you have many bidders if you clasify your items in the right spot to get the most money out of them dont wory about what you pay you get twice the money out of your items theres no way to get as much money for your items anywhere else thousands of people look at your items i have taken trash out of the neighbors garbage and sold it for 50 to 80 dollars people buy non working computers for 50 to 80 dolars with no memory or hard drives sell anything you want but clasify in the right spot or yll get scre w ed I buy items like this and resell themm for 3 to 4 times as much money so do your homework

EBay will have a fee for all of your selling items. There would be a listing fee.
A final selling fee %
Then there would be the fee`s charged by pay pal.
that is 4%
