I'll give it a try! Thanks so much!

I'm new here! 2 people have items listed that I'm interested in buying. One specifically stated in her advert to message her for shipping costs. I have done that 3 times over the past 2 weeks. She has never responded. Yesterday, her advert ended so I assumed that she had sold the books and not deleted the post. I found the items in a different advert and reached out to that seller for shipping costs. She hasn't responded either. This morning, I searched for the items again and was surprised to see the original advert back up. I've messaged both parties through the link on the advert but I wondered if there is a different way to reach them since they apparently don't respond to email or messages.
