Thanks @pk
So, even though it wasn't really a discounted exchange rate (the rate displayed the same but the effective cost was lowered by the coupon amount), would it likely not be taxable?
Like I said, I assumed that the coupons were only good towards the fees that the site (WireBarley) charges but they charge no fee if you send over 1 million Korean Won or more at a time.
But the coupon actually lets you lower the amount you even need to send them for the transaction (so 1 million KRW becomes 990,000 KRW with a 10,000 KRW referral coupon).
So, even though I put in that I want to transfer 2,500,000 KRW to USD, it only made me pay/send 2,490,000 KRW because of the coupon so I basically got either a 10,000 KRW discount on the transaction or 10,000 KRW for free but not sure which one is correct.
