it's way too simple - if I owe you $1 million and pay you on the 1 of March instead of 1st of January I'll make $10 000 in terest if I have the money in a bank (6% yearly interest for the sake of this argument)
so Topbucks will profit from this move and they can spin it any way they want to, that doesn't change the fact
now kids, can you guess who's the one to lose?
