Where can you get manufacturer coupons with no expiration date?

Manufacturer coupons with no expiration date are quite rare, but you can often find them directly on the manufacturer's official website, in print advertisements, or through promotional events. Some companies may also offer permanent coupons via their newsletters or loyalty programs. Additionally, coupon databases and community forums occasionally share links to such offers. However, it's essential to check the terms and conditions, as most coupons typically have expiration dates.
