I have a registry through Tupperware since there are a few things I would like from there (my mom had Tupperware and there were certain things that I knew I would love to have in my kitchen). Well, I received a box from Tupperware yesterday with items from my registry, but no indication on who the gift is from to send out a thank you card. I did some research, called customer service and found out, but figured I would pass along the information for others.
Call Tupperware Customer Service (in U.S.) - 1(800) 366-3800 and tell them you received a gift off your registry and would like to find out who it is from. Give them your information and the shipping number off the packing slip.
