Update: Discover has provided the following statement:
Our Cashback Match program, which automatically matches all the Cashback Bonus cardmembers earn at the end of their first year, continues to be popular with our cardmembers who are enrolled in it, and a competitive offer for prospects. There are no plans to make changes to the program at this time.
In my experience Discover is usually upfront and honest when asked directly about these sort of changes so while the mistake seems like a weird one to make my inclination is to trust that no changes will be made.
Original post: An astute r/churning member noticed that there is one mention of the Cashback Match on the Discover IT Cashback card being 6 months instead of 1-year. All other mentions there are still stating a full year of double cashback. (And on the Discover IT Miles card it’s still showing 12 months everywhere I can see.)
I checked on Internet Archive, and indeed it was showing 12-months in those same terms as of December 30th. They changed it within the past few weeks. It’s possible that they are in midst of updating this as we speak, or it was something they were looking into, or it’s entirely in error.
In any event, if I were interested in applying for the card, I’d do it quickly while the old terms are still showing.
