I have some gift vouchers, seems to be working fine.
Now, the problem is, that I am selling a $50 voucher at a discount price of $40.
 
What I do NOT want, is that someone would buy it, and then use the gift voucher to buy another voucher, etc, etc...
 
Is it possible to exclude a product from using a coupon / voucher ?
 
Thanks,

Yes it is, starting from new version 4.0.5 you may exclude/include individual products as well as product types from Product Coupons. We'll advise to read more about new coupon features at:

And then test them in our online demo:
