Listing posted several times by mistake

Sorry, unlikely to get any credit from eBay.

Tip for the future, write the listings, save them as you go. When you have a batch ready schedule them to go from Auctiva at intervals, even a minute is enough to make it easy to check them off as live, this eliminates accidental and profitable to ebay hiccups.

And the only way to be sure they have arrived at eBay is checking your active listings page, even eBay's mail confirmations of listing received is unreliable.

Sometimes stepping back a page in a browser can cause multiple events to be triggered not just with Auctiva.

edited by me to clarify scheduling

You can email ebay and ask, it doesn't hurt to try.
I've been refunded before on a duplicate listing...just be sure to end the duplicates first, asap.
