Initially I was worried, because I clicked on the first link (paid ads) to apply for my India Visa instead of official government website, which later I read in the government website which stated that visa should be only be applied though the official website. But that is after I submitted every documents and made the payment to indianimmigration.org.in. And there are so many comments made on how it was a scam worried me. I anxiously waited for my e-visa as they promised to deliver in 3 working days. I got my e-visa on the 4th day. I verified it in the government website, and it's valid.
I believe people out there might have the same concern, thus I am here to share my experience. I do not experience them as scammer. But weather they overcharged I am not too sure, as the website only provide 1 option for of visa application for tourist, which is one year multiple entry. If you are very much price concern, I suggest you apply through the official government website.
