Edit: @Brianpore Actually, my mistake, I bought from you through SF, not eBay.
You owe me five, actually. I made the comment as a good-natured rib but I'll happily cash in. PM incoming.
I have it set up to leave auto feedback as soon as someone pays and just double checked that its working.
That said, if you leave feedback for the same person around the same time it does not actually process as multiple feedbacks. I am not sure exactly how it works....
On further reflection, I'm a bit disappointed that you don't use adjectives in your feedback like those in your auction titles: SUPERLATIVE eBay buyer! EFFORTLESS transaction!
