madsqrl,
Thanks. No, this is not a bug. Also the gift certificate rows you see in the database that are $0 are "used up". Say someone has a certificate of value $100 and they make a purchase of $10, the certificate value is updated to $90. So certificates are used up until their value is $0. I think everything is working fine on your install.
I will be adding in the option you mentioned (With a seperate configurable email for this case). Thanks for helping with the testing!
