We need to redirect our customers from the checkout pages (of our storefront) to our main website.
1) "Traffic Control‑Bulk Redirectsby Refersion, Inc." app - redirects only from non-existing pages/routes
2) Shopify - URL redirects menu - redirects only from non-existing pages/routes
3) Inject a js code to 'theme.liquid' and 'checkout.liquid' templates - shopify plus is required for editing 'checkout.liquid', that is pretty expensive
Could you please help me to add redirection (especially the checkout pages)?
What is the redirection for? That will help give further info into things like _when_ you're hoping for it to fire. I am thinking you really don't want to redirect people away from checkout when it's not completed but maybe you do...
