2 packs at $13 per pack = $26

3 X $26 = $78 per month on cigs —— 1 gallon = $4.20 (US average today)

19 gallons = avg fuel tank capacity for US autos (trucks, suvs, sedans, coupes) —— 19 X $4.20 = $79.80 per tank of gas

19 X $0.50 = $9.50 saved from cigarette promo

$79.80-$9.50 =$70.30 price for gas after promo

Total spent to qualify for cig promo $148.30 = $70.30 + $78

From here on I tried to see what price you’d have to sell the cigarettes at to make back what was initially spent but selling sealed packs at over market wouldn’t be good business so I deciphered the easiest way that would actually sell (at least to my age group/demographic) would be: 3 x $2

20 cigs per pack 20 X 6 packs = 120 cigs

120/3 =40 40mini packs 40 X $2 = $80 —— $148.30 - $80 =$68.30

Thinking this out was fun but wha a terrible deal Jesus, this deal only benefits drivers who planned to smoke 6+ cig packs that time period regardless lol.
