6% at Two Retailers, 3% in One Category
This card is built for people who spend a lot at the big boxes. Pick two retailers for 6% and one everyday category for 3%, then set a reminder to re-confirm choices each quarter. There's a $0 intro annual fee for the first year, then $95, so make sure your 6% categories actually see ~$1,600+/year to clear the fee.
If you don't like tracking quarter caps or changing retailers, a flat-rate 2% card is easier. If you're okay with mild upkeep and shop Amazon/Target/Walmart regularly, the 6% buckets can add up fast.
