I agree that gas prices are insane, but this is still a very good offer. If you only fill up 8 gallons at the premium rate 3 times, you would pay at most $4.80 more that if you filled up with regular (you still need gas right? and I'm assuming that the difference in price between the two can't be more than 20 cents). So technically, this is a gift card for $5 and a "rebate" for $5, which is still nice (even if it does only get you 2.5 gallons of gas).
Thank you!!!
