The international variant has an unlocked bootloader, which allows for rooting, installing custom recoveries and custom ROMs.
The US variant has a locked bootloader which doesn't allow any of that. However, it contains some different radio bands for US-specific markets.
You can find all the differences here, if you tab through the different versions: https://www.gsmarena.com/samsung_galaxy_s9+-8967.php
How many people are going to comment before they do a cursory Google search?
Did you even try to look it up before challenging the price? Cause market price for this is $1K. I'm giving a discount. It's not me who priced the increased memory at double the smaller model. Even refurbished models are being sold for over $500 and this is unused and in the box.

what are the specs you want? Not to undermine these guys but...
Flagship from 2ish years ago
Thoughts on very good condition Tmobile LG G4? Has glass screen protector and this case on it currently.
I have one. 2 cases, a white OBLIQ case and a black/red Caseology case. Also has a tempered glass screen protector on it.
It was my wife's phone for about a year. In great shape except for the USB door. USB door has wear on it since you have to open/close it all the time. It's been in a case its whole life, so the rest of the condition is great.
It's also rooted and has Cyanogenmod loaded on it (which I can take back to stock OS if you'd rather). I'd like to get a bit more than $260 since it has all of that included with the phone, but shoot me a PM if you're interested. I can get you timestamps when I get home from work.
