ThankYou points are typically worth $0.01 each, although there are redemptions at lower values. The best redemption is for airfare where certain accounts are offered a value of $0.0133 each. The complication is that this higher value isn't documented, and I certainly cannot tell you if points earned with your corporate card would qualify. I would make the decision based on the conservative valuation of $0.01 each. On this basis it sounds as if you should try it for a year. Pay $75 to earn rewards worth $100 - $150+.
