Because your listings did not sell (during the free selling period) your listings are now being made available in the standard fee period, so yes, you will be being charged a success fee (if your auctions sell) I think the only way to get around this is to list as $1 reserve (to ensure your auction sells during the free success fee period) that is what I did.

Thank you for your reply... No I didn't say anything I regretted, but their questions didn't appear relevant or genuine (why would you ask about the battery "health" when the phone is as good as new?  Then tried to get me to accept a frivolous offer, that no one in their right mind would have accepted, and ultimately demanded I remove their bid(s) saying they weren't interested anyway.   I just feel/felt, having all those questions on my auction were a hindrance, not a help. I also became convinced they were playing with me...
