If the business runs a cashback loyalty percentage, every purchase you make earns that percentage of your order subtotal back into your digital wallet automatically — no action needed from you (a small number of accounts can also have a custom rate that overrides the store-wide percentage). It's shown as a simple statement on Earn Rewards ("For every $1 you spend you receive a X% back") — but this only appears when the Earn Rewards page itself is turned on, since the cashback block is nested inside that page.
