Remove Coupon / Gift Item Coupon

[magicstar]

Hello there,

I have Joomla 3.8.5 and VM3.2.12.

I would like to ask if possible to remove a coupon after appliance.

Also I have a FREEGIFT coupon (with zero value), but I don't know when a customer use it, cause it doesn't appear on invoice.

is there any solution in these two?

Thanks in advance

You can set coupons for single use ony (gift coupons) but rather than use the simple default VM coupons I prefer to use AwoCoupons which has far more options (and excellent support).
