Thank you. Do I contact the main branch or do I contact local McDonalds. thanks again

Ronald McDonald house collects pop tabs to help pay for families that stay there while a child is having a medical treatment.

Our school currently saves box tops and grocery recipts from a local store. Past officers have had children also turn in the metal pop can tabs. Does anyone else do this, and if so where can we turn these in at. Or is there somewhere that takes these as donations.?
Thanks
