I was at Joann's (fabrics) and I asked the clerk if I could re enroll on their mailing list. (If you don't use your coupon, they don't sent you circulars).
She gave me an application and I filled out both my street address and email address. She told me if I wanted two coupons, I could fill out another application for just online. I said that would be great!

She then took my application, copied the email address onto a new one and crossed it out on the original one.
Two coupons!
At Joann's!
