It's not a scam, it's a link from FedEx (or in my case UPS) to pay tariff and duty charges. Believe you me, I triple checked the whole thing and it was legit before I even considered paying for it. If you are shipping an item directly from outside the US, a lot of times those charges are left for you to deal with (resellers on eBay or Amazon for stuff from China would pay for those in advance, which is why it's not always normal). It's a bigger thing than it used to be, because it used to be that if the value of an item was less than $800 (I believe, it's been a min), there wouldn't be duties on it unless it was a big item or some other unusual circumstances. However, Trump screwed that up with the tariff changes, so extra charges are collected by the shipping company directly. The problem is that I wasn't warned ahead of time (I thought it was coming from the Philippines so the charges wouldn't be a thing), and that seems to be increasingly the norm for ordering directly from the manufacturer, given soo many are in China or countries we have decided it is a "good" idea to impose tariffs on (which the customer has to pay).
