This deal comes around regularly, so no "jumping" required.
The simple answer is to do some searching yourself of likely destinations. If you would pay less by buying points, then you should consider it. You would give up earning points, promo bonuses, cashback etc. so whenever the numbers are close you should book paid rates.
