I agree with this i automatically leave good feedback after a buyer has paid and then check their feedback to me to check they got the item.If need be i then respond to that feedback from them.Its true as sellers we cant leave a "problem" alert and thats actually really unfair.I refuse to be extorted over feedback ironically the one negative i got with my response " we refunded immediately as goods were damaged" is the best confidence a buyer can have from us.
