Out of the blue last week I received an email saying 'Thanks for signing up to sell with us. BUT I'VE HAD A SELLING ACCOUNT ON AMAZON SINCE 2004! The email came from noreply @ sell.amazon.com. I ignored the email thinking it was a glitch. But today I've had an email inviting me to list my first item and now I'm worried. The email was sent to the email address on my account. Has this happened to anyone else? I'm worried that Amazon will think I now have two accounts. Should I contact SS?
