If you purchase multiple items from one seller, wouldn't it make sense to leave feedback once?

If you have just purchased multiple items from one seller, in my case stamps or covers, wouldn't it make sense to leave feedback for that seller once rather then leaving feedback for each individual item?  After all, they were shipped at the same time, arrived in the same package and any communications you had likely dealt with that batch of items.  It would simplify the feedback process and should detract nothing from its effectiveness.

That's totally up to you if or how many feedback you leave. In some cases only some of the items might be as described so another buyer might want to leave more than one feedback. I believe that either way, the sellers positive feedback will go up by just 1 as all feedback from one buyer for transactions in a 7 day period is counted as 1.  At least that's how it worked in the past....but that is just for positive feedback, not negatives or neutrals.
