$1.00 off any one Trop50 59oz or Tropicana Pure Premium juice 64oz or larger.
Send a Mother's Day greeting to someone and you get to print a $1 off coupon. The greeting is sent e-mail to that person and they get a link to print a $1 off coupon as well. I sent the original greeting to myself. I didn't print either coupon so I'm not sure if you will be able to print both as the sender and the receiver.
