WHAT ADDRESS DO SEND MY RECEIPT TO GET A REFUND FOR LISTERINE WHITENING TEETH STRIPS, THEY SAY ON THE BOX?

THEY BOX DOES NOT SAY THE ADDRESS NOR DOES THE INSTRUCTION?
--------------------
bring them back to the store. what are you going to do spend 1/4 of the money sending the box back!!!!!!!!!!! think!!!!!! go to the store and get a store credit if you dont have the receipt, but if you do the store will take them back!!!!!!!
