Thanks to Holly for passing this along,
I was going through my Bed Bath and Beyond coupons and found a $5 off $15 that I wanted to use but was expired. I didn’t know if they still accepted those so I called the number on the coupon to ask. She told me that it was up to the store’s discretion to decide whether or not to accept expired coupons but that she could send a new one to my email right away! She offered a 20% off but when I told her I had a $5 off $15 she said she’d send that instead! Nice to know!
