Lets say i have a product for $30 and someone buys it at price ( $30 ). Now i raise my price to $40. If the person who bought at $30 ask for refund how much will he get ?? $30 or $40 ?? @matthewcoxy
ofcourse he/she will be getting the 30$ amount they paid for the item , as it is saved into the database the amount they have paid , and only that much amount will be refunded.
