SCAM 100%
This is scam 100%. It's plain and simple. International Travels Permit (i'm not even sure if they are real) is not authorized to issue IDP. So whatever paper/digital copy they give you will not be legal, and you'll get in trouble. Your IDP can only be issued by your local government. And maybe some associations that are authorized by AIT / FIA. But for my country, only the government can do that. I found out because I applied for 1949 IDP format with 3 years option, and this website issued that to me. Then I realized 1949 format can only valid for 1 year, but this website can give whatever years they want. After asking them about it, they ask me if I want to change back to 1 year. We're talking about convention that agreed by countries, you have to follow its format in order to be legal, you can't just anyhow change it when your customer requested it. If you complain about it like me, you'll get full refund. This is to ensure that you won't make noise and affect their other potential customers. For most people they are not aware they're holding a fake permit (as I said above, some car rentals employees or even policemen might not even realize it's fake), life goes on as normal. But when you're in trouble it's gonna be way more expensive (fine & bad record in that country). This is a lucrative business because they can still charge oblivious people like me, and only a small percentage of them ask for refund, which is still very profitable for them. Please stay away from this to protect yourself. Get your permit from local government or AIT / FIA authorized organisations. Do careful research. They take advantage of your urgency (since you're traveling to a new country and you need it desperately).
