Hilton Honors points as valued on average at about 0.4 cents each. But right now you can redeem them on Amazon for a better value, half a cent. You can use them for any purchase, including gift cards.
A great deal if you don’t plan to use your Hilton Points or if you have too many. This doesn’t last long usually, so act quick. The regular rate is only 0.2c so the current rate is much much better.
