Ok, so I just put something for sale in the yardsale without carefully checking out the value of it, and it turns out I'm cutting myself a pretty raw deal (145 new, selling for 60 used). I've had a few bites but haven't set anything up in terms of a sale. What do you think, is it too late to change the price of the item (say, raising it by 10 bucks), or is that "bad faith"?
