Hilton is currently running a targeted promo that allows you to buy HHonors points and get a bonus. You’ll have to log in to your HHonors account to determine whether you’ll earn a 20%, 30%, 40% or 50% bonus when buying points.
I was targeted for a 40% bonus which means if I buy 1000 points for $10 I get 400 bonus points at no additional charge. Likewise, if I buy the max of 40,000 points for $400 I get 16,000 bonus points. This works out to 0.71 cents per point. As always, I look to One Mile At A Time and The Points Guy to determine whether or not this is a good deal. Lucky (of OMAAT) values HHonors points at 0.4 cents per point while Brian (TPG) sets their value at 0.5 cents each. So buying points probably does not make sense unless you need just a few points to top off an award.
The promotion ends on December 22 at 22:59 ET.
