For future purposes you should leave a note/card inside package encouraging buyers to leave fb if they're satisfied with purchase.
Makes no difference whatsoever in my experience. I stopped wasting money after a few thousand business cards and the % of buyers who left feedback stayed the same.
Some buyers feel motivated to log back into Ebay once they receive their order and leave feedback, most (myself included) only feel inclined to do so if something goes wrong.
like everyone else here i leave feedback when something goes wrong or i buy from an amazing seller at 2pm pst and get the order the following day with regular shipping. Then i feel inclined to leave feedback and luckily for everyone else that i purchased before they then also get a feedback.
eBay should really just have a built in automatic feedback system for buyers after 3-4 weeks
Eb should send the buyers reminder with message like ''Everything ok with the order?
Select yes or no.
Ive always thought that after a period of time eba should automatically give you a positive feedback if the customer has not. If they have not complained then it has been a good experience, and like the sayng goes "no news is good news" so since they cant do it themselves ebay should give you what is inferred by the non feedback.
