Gift voucher/ coupon

[yoppo]

Hi,

This is actually 2 questions! I had gift vouchers available in my store. A person used a gift voucher (even though they had none) to pay for something around $300. I contacted the person and they said they didnt enter a gift certificate code. How is this possible. I have the newest version v1.38a.

The second question is: I disabled gift vouchers and you can see it in the payment section in checkout. The same person ordered something totaling $318 and again the invoice said gift certificate/voucher. How can this be?? It's causing a lot of hassle!

My site is www.thehandballstore.com

Regards.
