If you want to do it then it is good opportunity for you, and now people are buying and selling different things from bitcoin then why not you can do it. I always courage you and now in this forum wise, you can do publicity of your bitcoin gift cards.
Correct, i think many bitcoin users will be interested with this kind of idea, you should need to list all the stores accepting bitcoin right now all over the world to used your card spending with that store like here in our country most of the stores accepting bitcoin is cafe and lodge.
