A new way I have to save a bit of extra U.S. cash. I enrolled in that thing that most bank offers now. Every time I use debit etc, they will transfer 75 cents to an account of choice like a savings account. It doesn't take long to get 30-40 dollars in the account, then I transfer to a U.S. dollar account. Since the dollar an fluctuate weekly, when I see it go up a penny or 2 I'll transfer the money.
Our dollar is heavily influenced by the price of oil and gold, if they start to climb back up, it will help the dollar get some legs again!
