A new buy points offer from Hyatt came out this week. Not as good as the 40% we've seen the last few times but an alright offering if you need to top off your account for an award.
Offer details:
30% Bonus World of Hyatt Points when you purchase 5,000 or more points in one transaction. Full details Until May 23, 17
