oh and one tip about doing 1 listing for multiples.it is best if you do it as a buy it now item because if you do it as an auction the price doesn't change unless you have more bidders then the items you have listed
when you list it should have charge you it right then and there at the discount price. i'm not sure though cause i never paid attention to it before lol
is it done right at the beginning? is that a perk you get if you have a store? I dont have access to that but I am a peon here. lol
I just go in and manually lower my prices near the end of an auction sometimes in hope it will sell at the lower price. there is no sale icon for me to use.
dutch auctions are very confusing. All I know is that you don't get the highest bid price for your items. They explain it in 'help'.
Anytime you list multiple items without using a BIN, it is a dutch auction.
you have to have an ebay store.
I wouldn't lower auction prices at the end. Many people wait until the very end of an auction to bid anyway. Always list with the lowest opening bid you are willing to accept.
