Sign up on their website.
I've been told the mail ones are going to go away sometime soon. You can sign up in store to get text and email ones to your phone. They also have some new loyalty program where you can get 20% off your entire purchase always. I believe it's $29 for an entire year. They sign you up when you go in the store!
Downstairs the app, get on their mailing list. Don't count on them taking an expired coupon, sometimes they don't.
Download the app. They also send flyers in the mail and i have also seen coupons in magazines and flyers. Remember also, even with an expiration date they will still take expired coupons
