I am bad about leaving feedback. I always get it left but it certainly is not high on my list and sometimes takes awhile. When you are selling a lot of items, it is task enough to get everything, listed and then keep track of everyone who has/hans't paid and then ship accordingly.

I am much more concerned that the guy gets the product in good shape than him getting the feedback. Like i said he always gets it, but when time is limited, the feedback waits.
