Your username checks out, lol. At 5% APR, 30 days’ worth of interest on this $390 purchase is ~$1.63.
And if we consider that Nike is acting as a bookmaker in this case, the house edge for a bookmaker is around that amount anyway. Nike is likely to bake this edge into their margin anyway, but I don’t think it’s likely that you’d get a bonus of $1.63 if you win this bet, in this hypothetical.
