Since the site is running https-all-the-time, your site's root .htaccess file should 'support' that. Make a backup copy and add the following clauses close to the top of the file to 'force' the access to https://vinyldecalsuperstore.com/{whatever} when the access is made as

vinyldecalsuperstore.com/VDSstore/{whatever}
http://vinyldecalsuperstore.com/{whatever}
http://www.vinyldecalsuperstore.com/{whatever}
https://www.vinyldecalsuperstore.com/{whatever}

Code:
RewriteCond %{SERVER_PORT} 80 [OR]
RewriteCond %{HTTP_HOST} ^www\.vinyldecalsuperstore\.com$ [NC]
RewriteRule (.*) https://vinyldecalsuperstore.com/$1 [R=301,L]
