Samsung Gear S3 Classic or Gear S3 Frontier (New) at Samsung.com (Discover Deal) [YMMV] $212

I picked up on Samsung.com when I saw a Discover card deal that takes $100 off the current price of $299.
You could apply the promo code at checkout if you can find the Discover deal of $100 off.
Mine was $212.49 after tax.
