I think Target has cracked down on those who went to Target and bought Disney Tickets from their "Gift Card" selection and getting the 5% back. As I understand it, you can't get the 5% anynore.
But since the last few posts have been talking about buying from LMT (Last Minute Travel) or Sam's Club directly, a Target card won't work, nor would a Disney gift card.
My suggestion is to look at your current Credit Card offers, as many companies have jmped on the fact that VISA is now accepted at both COSTCO and Sam's Club, and offering things like extra cash back (one will give me 5%) for "Membership Warehouse/Wholesale Clubs" purchases through the end of the year. So I can get the LMT/
Sams Club price, charge it to my Visa card through Sam's Club, and then get my 5% based on the special offer. One was from Chase VISA.
