A DoorDash discount lowers the delivery price, not necessarily what you spend. Compare the same basket ordered direct, with fees, tips, and DashPass included.
A 3%/1% card beats a flat 2% card only when half your spending lands in its categories. Three households, the break-even formula, and how caps change it.
A second card needs a job. Assign each purchase to one card, count each dollar once, and compare the pair with the best single card after fees.
