Nothing more perfectly illustrates inflation happening in front of our collective memory better than this advertisement.

We’ve truly fallen from grace when a $5 bill no longer gets you 12” of questionable meat on something that can’t legally be called bread.
Oof. It use to be $5 footlong 😂
The song just hit..
‘5 dolla, 5 dolla, 5 dolla foot long!’
I had to look it up, but that's bad.

FYI, the $5 footlong promo last ran 7 years ago. To get to $6 6" from $5 12" in 7 years is just over 13% annual inflation.
Do you still believe the CPI numbers?
No way! Is this for real!!!? 🤯

Didn’t you get a foot long for the same price before? I dunno since I haven’t had subway in years
Yeah, used to be $5 footlongs
This is not the halving you are looking for.
That is really crazy. Wouldn't pay that for a Sub!
