One thing I haven't seen mentioned is that if you sign up for Travelocity Preferred membership, you will get $50 off of every Last Minute Deal you book on the site. The booking must be made on Travelocity though, not Site59, to qualify for the discount. I also don't see any mention of package minimum to qualify for the promo code, but I could be mistaken. Best to check with Travelocity directly.

I believe membership costs $29/year.
