If you're already thinking about lunch on Thursday, here's an idea that won't cost you much: $1 subs. Sound too good to be true? On April 21 only, it'll be a reality at Jimmy John's first ever Nationwide Customer Appreciation Day!

The restaurant chain will thank its customers by offering $1 sub sandwiches-- but there are a few rules you need to follow:

- The offer is ONLY good in store, from 11 am to 3 pm.

- Sandwiches #1-#6 on the menu, as well as BLT and Slims are all available for $1. If you want it on JJ's 9-grain wheat bread, there may be an extra charge.

- $1 subs are limited to one per person. If you would like more than one $1 sub, you can go through the line as many times as you like.

- The promotion is nationwide, but it's up to the owner of the store if they are participating. To find a participating store near you, click here.
