I send up to $100,000 a month to overseas factories in China. I've been doing MS for monthly spending minimums but I am trying to see if there is a worthwhile way to earn points with the amount of money I am already sending.

While some factories have US bank accounts, most only accept T/T and WU. For small purchases under $5,000 with factories that have accounts in the US, I will probably use BB. I've looked into using WU for sending money to a Chinese bank account, but it does not look feasible.

Does anyone have any suggestions for killing to birds with one stone and getting money to China?
