Some people think feedback is important , some dont, thats their choice. But to those that do and check everyday, forever chasing the perfect score it means they do worry about scarring their perfect score and take pride in what they do, even if it is only a little ego stroking.

So they do try to be the perfect seller, even though that level of "perfection" is not necessay to be sucessful, it is beneficial to buyers and the overall attitude of the public to Ebay sellers..That cant be a bad thing.

On a pure business policy option of whether to leave it first or later., its a simple choice. Do what makes your system/admin smoother, and feels best and if your business/feeedback received is not adversly affected, stick to it. It is your business, therefore your choice. Like every business decisions there are always arguements for and against, and theory does not always match reality.
