<prompt> Human: Credit cards often offer x back on purchase from partner retailers. Whats to stop an individual from purchasing an item from said store for the cashback bonus and then returning it later? Would that person still receive the bonus reward?Example:BOA is offering 20 cashback on purchases from 1800flowers.com. John buys 100 flowers for his GF for Valentines Day. They break up suddenly, and John cancels the order. Does he still get 20 cash back at the end of the month?  <response>: No. Just like reward points are earned when a purchase is made, they are taken away when a return is processed.
