I usually will wait until the listing is almost up and just fix in auctiva and relist from the auctiva saved listing. (unless it needs urgent repair in which case I usually just end the listing and fix figuring it is not worth 5 cents to fix 2 times). Of course, that depends on your ebay plan also if it is worth the time involved in fixing two places.
I guess I am somewhat lazy with doing the fixes. .
