This doesn't surprise me, and I think most were already doing a lot of their own promotions (which is why a lot of them bitched when they were forcing the $5 footlongs again). But Subway has raised their prices (even a fucking veggie is almost $6 now), so they're getting worse. They aren't great but, based on the sub shops here (Phoenix), they're far and away a better value than pretty much anyone else. Most other places are $10 for decent sized (similar if not usually smaller than Subway footlong) sandwich. Jimmie John's is like $8-9 for one that's between a 6 inch and footlong Subway. Firehouse is $10-12 for a footlong sized sub (which seems to be about the norm for other chains here), and in my experience worse than Subway about fucking things up (since they make it behind the counter where you can't see you don't know what's going on and what, plus they like charging for extras). Schlotsky's has a lot more variety of food which is nice, but they were fairly expensive I thought (and holy shit at Cinnabon's prices). Jersey Mike's was stupid priced when I went there so I haven't been pack. Haven't tried Potbelly yet, or "which which", and there's others that I forget (and others that I've eaten elsewhere, Planet Sub, Quizno's, Chompies, Mr Goodcents). Panera Bread and places like that are in my experience way overpriced and I don't consider them equal to sub shops either so I won't even bother remarking beyond that (which I like soup in a bread bowl and some other stuff at Panera, but they're damn overpriced for what you're getting).
The delis at grocery stores and stuff are a crap shoot too. Some are ok priced, but there's a bunch of them trying to charge over $5 for simple 2 standard sliced bread sized sandwiches (Which is like a 6 inch Subway sub if that even).
Oh and of course the Subways are a crapshoot. Some are terrible, some are decent, most are meh.
Haven't gone to a subway on purpose in many years. When their subs ended up turning into mostly bread sandwiches I lost interest. Yes, they are one of the best for adding toppings but I prefer something with a bit more meat.
Uh...
They used to be reasonably priced on double meat and stuff. Now sure it might not top these magical 2 foot long New York deli sandwiches for $3 or whatever bullshit people always claim, but in my experience they'd still be cheaper with paying for extra meat than most other places are for their standard subs and they'll come with more meat than those do most of the time. But with the increased prices it'd probably be about equal in price or meat you get per $.
They also have wraps now that you supposedly get double meat on (so the meat to bread ratio should be way up). But you probably would want to make sure to remind the employee that it comes with double meat standard because Subways employees tend not to be the best and some I think the manager is a stingy asshole so tells them only to put on some small amount unless the customer requests more.
I haven't had Subway in a really long time. I always felt like complete crap after eating one of their footlongs.
Eating a footlong should be quite a meal for most people, so I'm not surprised at that. And if you have a soft drink and/or chips, then yeah, you'll be feeling pretty shitty from stuffing yourself.
