Exclusion Update: X Money updated its merchant category code (MCC) exclusion list in September 2026, officially adding MCC 5300 (which covers wholesale clubs like Costco, Sam's Club, and BJ's) to the list of non-qualifying categories.
Retroactive Removal: Purchases at wholesale clubs no longer earn the 3% promotional cash back rate, and past rewards in excluded categories have been retroactively removed.
