I'm going to comment on this and hopefully this will be the end of it.
Not every infraction is going to be cut and dried & a clear cut example. Sometimes there's going to be judgement calls. I, personally, support the infraction in this instance and really wouldn't mind if all questions about sales were taken to email or the PM system.
The burden is on the OP to spell out what's up with their item for sale. They should provide as much detail as possible, in the original post. Chit chat back and forth should be reduced to a minimum. Sometimes questions are legitimate. If you aren't directly going to buy something though, keep out of the thread.
