(Money back = rebate): An instant rebate is a marketing ad that works just like any sale price. A mail-in rebate relies on layers of inconvenience such that the percentage of consumers who actually end up having the rebate redeemed is somewhere like 20–68% (20% of all sales, but 68% if you consider only the consumers who likely only bought the product for the explicit intent of redeeming the rebate).
