👉 Bargain math is a method to evaluate the value of a deal by comparing it to a reference point or a "fair price," often determined by the cost of alternatives. It involves calculating the difference between the actual price paid and the expected or fair price, then assessing whether the deal is a good value based on this difference. For example, if you buy a $100 item for $80, the bargain math would show a $20 savings, suggesting the deal is quite good unless there are other factors at play, like added features or convenience. Essentially, bargain math helps you determine if a deal is worth the money spent by quantifying the perceived savings relative to alternatives, guiding you in making informed purchasing decisions.
