Yeah.....that's one of those too-good-to-be-true things. The shop supposedly sells t-shirts, but they seem to list nothing but crazy cheap tech. I did a little digging into the domain/site and found some "scary" things. I'm going to go ahead and say
DO NOT BUY.
1. They're running code that attempts to detect visitor's email addresses. Sadly, sometimes this kind of thing works thanks to some of the "make everything easy" things that some browsers do. I can't figure out how it's doing all of it, and I don't really have the time to dig into it further than I did. FWIW, Brave Browser seems to be very good at blocking this kind of thing.
2. The code on the website is weird. They're using a mix of different methods to do the same kinds of things in different places. That's not "wrong", but it's a bit odd. I guess I do that some too, but I don't like it.
3. There are a lot of references to "omesaas", which is very similar to "onesaas", which is an Intuit product that connects e-commerce software to QuickBooks. It almost looks like they're trying to make a half-casual observer who digs just a bit not notice it isn't the same thing.
4. The address given is the Student Center at St. Louis University. Except that it says "Louis, MO", which doesn't exist. I assume they meant St. Louis.
5. The JS console spits out Chinese text.
I'm convinced it's a scam. At best, they're trying to do tracking and email collection.
I did email Morningstar so that they know, and apparently it's not the first time this has happened. They also said they can't do anything about it, which implies that it's foreign.
So, yeah....real strong caveat emptor on this one. If you're going to try to order one, use a disposable card that can't lose you more money than you spend on the thing, close it after the first transaction, and be ready to pursue a charge-back.
ETA: sometimes, there are upsides to being a dork.
