I have purchased and used several "international" versions of Samsung phones that were unlocked.

Unlocked simply means that any SIM will work, as the phone is not locked to a specific carrier.

One needs to be careful as not all unlocked phones are compatible with the Verizon network. This is because Verizon requires certain technology (CDMA) for the radios inside for US locations. Outside the US, those Verizon phones roam using GSM cell carriers.

International models also sometimes have unique features not offered in the US. My Samsung S7 Edge had slits for 2 SIMs, permitting me to use my US phone number as well as a local number when traveling in Asia and Europe. I purchased a local travel SIM in some countries to avoid roaming charges.

These phones lack US carrier applications and bloatware - apps that use memory. I had no issues on ATT, but was able to manually install a few ATT apps that I wanted.

Finally, the international version may have a warranty that is not honored in the US.

Bottom line, you need to understand the details to make sure the phone will work as expected, and what to do if something goes wrong.

Yes, sometimes prices can be very good. I purchased mine from reputable vendor on eBay, for new, unlocked, factory sealed phones intended for the UAE. They were shipped by a Houston vendor.
