Regarding on the Amazon gift certificates, you have to inquire it directly to Amazon. They are the ones that will be giving out the $25 GCs. Ones you referred a friend, and your friend got the device it will show in your myooma page the amount.
If you have other questions call us at our support line 1-888-711-6662 0700-0700 PST Mon-Fri and 0800-0500 PST Sat-Sun
