Is bmwpartsguy a legit store?

I recently bought some new BMW coils for my HP4 at Euro Motoelectrics, and everything works perfectly fine the new coils look exactly like my original ones that came with the bike that I pulled out.

But I wanted to see if I could have bought these coils for a lower price if I did more research and when I searched on Google for the coil part number listed on Euro Motoelectrics: 12 13 7 710 874 / BMW, this store came up: https://bmwpartsguy.com/ and they were selling the coil for almost $50 lower than Euro Motoelectrics and my local BMW dealership parts store and other BMW dealership parts store like Max BMW. Also bmwpartsguy's site mentioned these coils being "Made in Germany" but the brand new BMW coils I got were "Made in China" and the original coils I pulled out looks to be made in China also due to both coils (new and old) having the "CN" laser etched (or w/e method they used to put on these labels) on top of the coil with all the BMW logo, parts number and other various labeling.

Anyways I tried searching online for keywords like "bmwpartsguy store legit" or "reddit bmw motorrad bmwpartsguy" to see if any forum post mentioned this website/store before and the only one I could find is this the advrider forum post about asking the same thing: https://www.advrider.com/f/threads/anybody-buy-from-bmwpartsguy.1757083/

First post mention its a scammy looking site (I agree it does look so sparse that it does look scammy).

Second post mention its a guy they know and hes been to his local shop and the store owner has a YT channel, looking at the channel it has the same logo and is not a dead channel: https://www.youtube.com/@TheBMWGuy

So my question is, has anyone ever heard of this store and if so have you purchase anything from him before? Even though I don't need to buy new coils as I already have them, but for future reference I would like to know if this online store are legitimate to buy from and if there are other online stores that sells authentic BMW parts that you would recommend me to take a look at for cheaper than dealership prices.

Thanks for reading my long post.
