If you eat only what you cooked consistently, then yeah, chances are it's significantly cheaper per meal.
12-pack of Crossiants at
Sam's Club - $6
Deli sliced turkey, 1 pound - $13
Bacon - $7 pack, but you can find the fully cooked bacon for $4.50
1/2 pound of cheese, deli sliced - $7
Toppings/Condiments - Let's assume $10 bucks, depending on tastes.
Large bag of chips - $4
$42-52 bucks spent, should make 12 sandwiches + handful of chips on the side = roughly $4 per meal, give or take some loose change.
That same meal at Jason's Deli is going to run you about $8-10 bucks.
