I hope they re-partner, but I doubt it. 20% is an insanely great discount for such a common expense. I'm going to miss all of those little green refunds all over my CapOne account.
Unless something better is announced, I'll probably switch to Citi ThankYou Premier for 3x, at least when Freedom doesn't have a 5% back on rotating categories for transportation. The partnership with SPG might be valuable to add on as well while the program is still alive.
