Travelocity is offering 20% off a minimum $800 hotel purchase using promo code AMEX20H (purchase by August 16 for travel through December 31). Price is reduced instantly.
Then, if you’re traveling by September 30, the American Express Link, Like, Love promotion can get you another 20% off in the form of a statement credit. (Minimum $350 spend and 3 nights. This can only be used once per cardmember.)
These two combine for a 36% discount.
Sadly, I don’t believe that the Travelocity American Express is eligible for the Amex Link, Like, Love promotion (because the card is issued by Barclays), or else you could get another 10% rebate on your actual spend. Wow.
But without that, an $800 3-night stay consumed by September 30th will cost you $512. Not bad.
