Sharing Google Store credit within family

Looking to get my wife and I 11 Pro folds. We'd be upgrading from our 9 Pro XLs. Is it possible for me to order, get the $350 in store credit; then her order and use my store credit while also claiming the free watch? I assume we'd need to do it on our separate google accounts, but since our accounts are linked I don't know if there's a way to share the credit.
