Ranked by effective rewards rate — points, miles, and cash back normalized onto one comparable scale by WalletFlo's OneCard engine.
A "5x" card and a "3% back" card can't be compared by their headline number — points and cash aren't worth the same. The OneCard engine converts every card's reward into an effective cash-back rate, so this ranking reflects what you'd actually get on online shopping, not marketing math.
The best card for online shopping is only one slot in your wallet. WalletFlo picks the right card for every category automatically and flags the rewards you're missing.
