Not really. The subjective monetary value of whatever you might spend that money on is most likely going to be less than the store’s listed price. To give a more obvious (extreme) example, imagine if you got a $30 gift card to a store that sells individual grapes for $2 each. You can buy $30 worth of grapes from them, but 15 grapes are not worth $30 to any sane person. Hell, maybe you don’t even like grapes and they’re completely worthless!
