Hi Kevin,
Unfortunately the gift codes that were offered as a bonus gift when purchasing MinecraftEdu are no longer available. We kept them available for two months after the sales of MinecraftEdu ended, but as we were no longer a part of Minecraft in Education, we had to move forward and couldn't legally get and distribute the gift codes any longer.
The problem with them was that they were not a product like MinecraftEdu licenses were, they were something TeacherGaming LLC chose to offer as a bonus, but now as Microsoft owns the rights for MinecraftEdu, they have no legal obligation to offer the gift codes.
I am very sorry for any inconvenience this may cause, but there is nothing we can do to help with the gift codes at this point.
Please do not hesitate to contact us if there is anything else we can do for you.
Thank you for your understanding!
Best regards,

So gift codes are a not go, we have 30 seats for out Tynker account I guess I would have to figure out a way to get funds to get 30 regular Minecraft versions onto our laptops. At $35 a pop here in Canada its not cheap. I also emailed Microsoft and they will not support any mods. Too bad we have Minecraft Edu and cannot link it to Tynker. My kids here would love to make that happen, it would be amazing. Thanks for your help and suggestions, really appreciate it.
