The sales adds allow you to send an e-mail not a personal message that is why they don't show in "My Messages"
Although it sends an email, it does it via the website rather than the user's email client, so it doesn't appear as a sent message in your normal email client (Outlook in my case). This means you don't get a copy if the site doesn't post a copy to your sent messages. If this is how its supposed to work, then OK. But it would be handy having a copy of the sent message.
I can see the way round this is not to use the link on the ad., but just send a PM to the seller. Alternatively, you can use the link to get the sellers email address and then send a message from your normal email client.
