sarmaleDo you pay with cash or card?
US: Credit card only, almost exclusively using Apple Pay. If I somehow obtain cash, I deposit it so that I can spend it using a card instead and earn the rewards. I actively use about half a dozen cards, choosing the right one for each transaction to maximize rewards.
While its solid you’re into the efficiency of it all, as an outsider it seems like an added headache to remember which card would be best for which outlet / type of transaction. I personally just maintain a few cards and only switch once I’ve reached about 50-60% the limit.
