This is probably not the site you are looking for!
You attempted to reach https://www.dmsmerchandise.com, but instead you actually reached a server identifying itself as https://www.dmsoft-wy.com. This may be caused by a misconfiguration on the server or by something more serious. An attacker on your network could be trying to get you to visit a fake (and potentially harmful) version of https://www.dmsmerchandise.com. You should not proceed.
I think you need to look closely above at what Google and FF has to say in the error.
This certificate is installed incorrectly or for the wrong domain.... again it matters little what Comodo says as no one will shop at your store..... Just an FYI also, that you have accessed the site many time and have cached its IP and are probably NOT displaying the error as a result.... But until you posted I never have.
