as a seller, its only natural for us to want a sense of closure, knowing that everything was satisfactory both on our end and at their end, and that we did a job well done. I'm afraid its true though, that there is a portion of the ebay buyer population who just choose not to leave feedback, for whatever reason..
the reason i find it a little frustrating is simply not knowing whether or not they received the item, or received it well. after a while, i assume that if they hadn't received it, or received it damaged, they would have notified me, so i have to assume all went well.
i remember one case, i looked up a buyer's "feedback left for others" section, (surprisingly, this buyer had HUNDREDS of feedback left for them) and they had never ever once left feedback for anyone-NOT EVEN ONE!!!
😮
i found this to be a little uncourteous...sellers were nice enough to leave good feedback for them, and they were never courteous enough to return the favour, i'm surprised at how many sellers actually did leave feedback first, or maybe did what you did, and left it in the hopes of receiving it. i can just imagine how many other sellers there were that never left feedback.
bottom line, you're certainly far from the only one, instead of sending reminder emails, maybe try a personal note in their invoice letting them know you appreciate any feedback left and that once received, you will reciprocate, or even in a personal thank you email after the sale. I've also seen it on auction listings. that's pretty much the best you can do, in my opinion...:-)
