Last month I paid my DirecTV bill with this card and it appears to have rebated at 5x.
It codes as "miscellaneous" on their Website, just like my Internet provider, yet rebates at 5x. Anyone corroborate this? Makes me regret not reading the Wiki more carefully before, but better late than never.
Edit/Update:
it's always wise to search; it should be put into the Wiki that DirecTV codes for the 5x.
