the odd occasion I have sold. I spent a lot of time making sure everything was correct the first time. That way no revision has to be made = more time the listing is veiwable in a search = more chance the item is sold.   Its like the old measure twice, cut once rule

It's a good philosophy. Sometimes, though, even after checking the listing twice, you spot something that could be changed. I'm a bit particular now about making sure my listing is accurate to prevent problems post-sale.
