Hilton’s bonus for buying points is back! With Hilton’s offer you can earn a 100% bonus when you buy 10,000 or more points in one transaction by February 9. This time the promotion does not see the doubling of the annual cap on buying points which means you can only buy up to 80,000 points. That 80,000 cap does not include the bonus points so if you max out this offer and buy 80,000 points you’ll receive 160,000 into your account.
