Post a question stating what the correct answer is. If you link the question to the product then anyone looking at the product will see the correct answer before they see the incorrect answer. That being said we try to give the correct answers but sometimes we make mistakes or our sources are incorrect and sometime we misread the question

Marvin, Buds does not have an open field to do this currently. It really should be an option within the answered question field. Currently one can only post the correct information and hope the original asker/answerer sees it.
