I don't know the answer but thanks for reminding me! I thought they said they mailed or emailed them...Is the end of the cycle 9/30? I think I am like $4 away from the next certificate, need to check my account!
They do mail them, but you can get them a few days sooner my logging into your "rewards" account online. I wish they'd let you use more than one at a time, though!
