Redirect from where? One solution does not involve WP at all (at least until the destination page gets requested). First create a simple static .html page with a refresh meta tag. Sample HTML:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="refresh" content="7; url='https://www.your-domain.com/store/'" />
</head>
<body>
<p>You will be redirected to our store soon!</p>
</body>
</html>
In your .htaccess file, set up a redirect rule from where ever to this static .html file. The file then redirects to the final destination.
