Hilton Honors today launched a promotion on purchased points with the highest bonus and increased maximum cap for purchase for a limited time.
Buy Hilton Honors Points With a 100% Bonus
The bonus points promotion is ongoing through November 22, 2022. During the promotion, Hilton Honors members who purchase at least 5,000 points and above, will receive a 100% bonus.
Keep in mind that this offers seems to be targeted with some members receiving a lower bonus on their account but to know exactly, it is best to check your account.

Hilton Honors Increases Purchase Limit To 160,000
What is great about this promotion is the number of points that can be purchased. Usually, the maximum Hilton Honors points available for purchase are capped at 80,000 points per calendar year. But this time, it graciously increased the cap to 160,000 points. Meaning with the 100% bonus points, members can receive up to 320,000 points.

Cost of Hilton Honors Points
Hilton Honors normally sells points at a rate of US$10 per 1,000 points increment. That is around 1 cent per point. And with this offer, members can purchase 320,000 points after bonus only for US$1,600 (0.5 cents per point). This is really great opportunity and offer to buy whole block of points.

All taxes and fees are included on the rate.

Redeeming Hilton Honors Points
Hilton Honors does not have an award chart instead it uses dynamic pricing. This means the award point rates can vary depending on dates, times and seasons. But typically, the cheapest Hilton properties start with 5,000 points per night up to a million in destinations like the Maldives.
As you can see below for an example, the point rates at Conrad New York Downtown. The hotel has a paid rate varying from US$500 to nearly US$800 on a deluxe suite.

But with 320,000 points you are able to stay up to four nights. Whats better? Hilton Honors elite members are able to book a fifth-night free on award redemptions. So you can basically stay 5 nights for just US$1,600 instead of spending nearly US$4,000.

Summary
Through November 22, 2022, Hilton Honors is offering 100% bonus on purchased points. On top of that, the maximum cap to purchase is also increased to 160,000 points from the standard 80,000.
This is a great deal offered from Hilton Honors recently where you can spend points on hotels stays with a lower cost ratio.
