Amazon has tons of bands for around $8-10I was able to get the Watch 7 for $97 from Samsung when I ordered my S25U.
I like it a lot, but I wish they would have given a choice of band size like Apple does for the Apple Watch. The big band size Samsung sends is pretty big on me and I would prefer the small size. I hate having to spend more money on a new band when Samsung should have given me the choice to begin with. New bands at Best Buy are insane around $50. Who they kidding with that. I will just have to shop around for one.
I never buy watch bands from Apple for Samsung. They are over priced IMHO....
