This plugin automatically offers a discount coupon for every purchase made by setting a expiration date in days. 
This plugin manages to automatically give customers a coupon for each purchase they do so as to entice them to make the next purchase. You can set the discount percentage, the days of validity, the description of the coupon and you can send everything via email. Then you can enter the subject and body of the email.
Truly wonderful.

WC Give a Coupon

Grazie a questo plugin sono riuscito a dare automaticamente ai miei clienti un coupon per ogni acquisto che facevano così da invogliarli a fare il prossimo acquisto.

Wonderful

A plugin that automatically offers a discount coupon for every purchase made by setting a deadline.

Add a simple “Send this order packaged as gift” checkbox to the checkout. Optionally it is possible to set a price for the packaging.
If you want multiple gift packagings and other fancy stuff this is not the plugin for you … this plugin is intentionally very lightweight to fit directly into the WooCommerce user experience.

WC Gift Packaging

Hi there!

Many thanks to your lightweight plugin!!

It is easy to use, also lightweight.

WORKS FINE but, I have found some bugs in your plugin (about translations)

UPDATE: The plugin is abandoned so, we had released a similar plugin to this fixing the bugs and giving the ability for free gift wrappers!!

Gift Wrapping for WooCommerce

Easy, lightweight plugin, doesn't matter that you to updates years

This plugin adds a 'Send this order packaged as gift' option on the WooCommerce checkout.
