So I have gift certificates for $25, $50, $100, and $500. I have triple checked that the "Products Price" is correct for all of them. A customer purchased a $25 gift certificate. I was paid $25 in PayPal. Yet, their GV balance shows as $50. The person is in the United Kingdom but I would think that doesn't matter since the dollar sign is showing next to the GV Balance. I am concerned that people buying $25 gift certificates will be able to spend $50. I'm going to go into phpMyAdmin to change the $50 to $25 but what to do I do to stop this from happening short of disabling gift certificates?
