For those who hold buyer feedback hostage, I have a question.
If the buyer is unhappy with his purchase, but provided you timely payment does that change how you rate them? Seems unfair to the buyer.
That method means that the buyer is thus responsible for the entire transaction. I leave feedback immediately for the paying buyer because I expect them to provided a fair assessment of me and not worry about how I retaliate. I did this before the feedback change too. I realize that most didn't follow this example and eBay changed their feedback system because unhappy buyers were scared to leave truthful feedback because retaliatory sellers would leave negatives for buyers who completed their half of the transaction.
That is like a chef deciding if he will cook a great meal or a crappy meal based on a patron's pre-meal evaluation.
