nice project and interested to buy itunes code but your account is newbie, we need proof if you offer legit service.
Thank you, but I'm not sure how I can prove that. The user who bought something could provide such proof
But if you have any idea how I could do that, let me know and I'll do so.It seems like an interesting project but since your still new, wanted to let you know that you have a big competition ahead of you, in which has been doing this for some times (not sure if your aware of him).
Thank you! I know, but I just wanted to make something that would work. I saw some websites which sells cd-keys like https://eternalsummersale.com or https://steambitshop.com, but the first site's dead - you can't register and the other one has high prices (and better offer, but still working on that).
Anyways since your still relatively new, would you give some voucher to those who are Hero/Legendary in the community with good trusts so they would give an honest feedback on your services?
That's a good idea and I should do this in first place. If you write your bitcointalk.org username in the "Discount code" field, you will receive 6% of the item's price back to the wallet you sent money from. I don't have a better idea since BitPay doesn't offer an ability to reduce price before payment. What do you think?
Also you lack SSL certificate so I advice on getting one as well.
I'm working on adding an SSL certificate, but this one will be hard, because my hosting service doesn't allow to connect third-party certificate and doesn't offer one to buy, so I'm using CloudFlare, but it doesn't seem to work too. But I will fix this, I hope 
Another thing is, 6 confirmations before sending the code is very long waiting time since most merchants do this after just 3 transactions (at most) and as result, your going to pay a lot of extra 5% discount codes if you go with this plan.
You're right, I'm going to change to 3 confirmations.
