Today is when sellers can no longer leave a negative or neutral feedback for the buyer.
Buyers however, can still leave whatever feedback they feel is warranted. However, buyers who abuse this by extorting the seller will be penalized or removed by eBay.
While we are discussing feedback, eBay does not do a adequate job of educating the buyers that the Detailed Seller Ratings (DSR's) are used to reward or penalize the sellers.
Good is not good in eBay's eyes, only excellent, so if the seller has done good job describing the item to you, packaging it, communicating and shipping in a timely manner with fair handling charges, give them excellent. Anything else is a negative to eBay.
Just because you did not have to write to them does not mean that they did not communicate well with you. In fact, if you did not have any questions, then they did a GREAT job of communicating what they had to sell, the condition and terms.
Shipping, postage, or freight is expensive today and going to get worse. Be sure you are rating the seller and not the Post Office or freight company when you zing them for costs.
Surprisingly, even those who offer FREE shipping will get "good" on their DSR rating for shipping costs, which tells me that the customer does not understand what I said originally. "Good is not good in eBay's eyes."
