I wait for them to do either b1g1 or $7 subs, then get the beast sandwich - half a pound of assorted meats, plus bread cheese veggies and toppings. plus double meat for $3 more.

for $10 I get roughly 1500 to 2000 calories of subway sandwich, and I looked it up and its far cheaper than buying it ala carte at the supermarket and making one myself

meats about $5 on average at the store, a loaf of bread equivalent to subway is probably $1 to $2, and the condiments and veggies are several bucks
