Store inventory/listings that were started in your store will relist by themselves; and yes with no credit for relisting.
If it's been an auction you have to move it to your store. I think there is a fee again. So what I do is check check the ended ebay listing, (cause I forget where I started what, on here or ebay,) check the fee for lising in the revise mode and if it's more than 6cents I either disable what's making it cost more in ebay, or I forget it and come back to Auctive and create a new listing for that item. Often times it costs less to do it that way.
I have edited some store items in ebay if they were started there before I joined Auctiva and there isn't usually a charge...unless like I say it was an Auction before.
An auction in your store costs more to list than store inventory. And it may qualify for relist refund....maybe. Buy it now adds a fee too on the first listing, but not when it relists.
Just a store listing created on Auctiva with as many pics as you want and have in your images on Auctiva is usually 6 cents.
I hope that made sense.
Bottom line, go through the revise listing on ebay and if it's going to cost more, let it go and come back here and create it.
Every item I have is different and I currently have 59 listings, so I know it to be less work doing it here than there.
Ask away I will help if I can.
