JMR.codes

A simple plugin with no settings or overhead. This adds “Bulk duplicate” and “Bulk delete” actions to your WooCommerce coupons admin list. Generate up to 500 duplicate coupons in a single batch, copying every WooCommerce field and any meta fields generated by other plugins.
When generating, an “Advanced options” panel lets you set the generated code length (3–96 characters), override the expiry date, and optionally remove email restrictions so the new coupons can be used by anyone.
A “Delete all unused” button next to the list filter removes every coupon that has never been used, after a confirmation dialog showing the count and a short countdown.
