Hilton Honor launched late May up to 50% off Mystery Discount for buying points that ends on June 23, 2017.
Hilton Honors members are eligible to purchase up to 80,000 points every calendar year, although some accounts may have this limit occasionally lifted (usually doubled) during these sales.
You can access the offer on Hilton’s website here.
The standard price of purchasing 80,000 Hilton HHonors points is $800. Those that have their discount set at 50% can purchase them for $400. The price of a point at this level is half a cent.
