What surprises me is that anyone bothered to reply to posts by such lazy brain people. Can you guys tie your own shoes? Did it occur to you to look at the last ex date and add 90 days to it? Do you need an exact formula or to be told the web page where such information is available? Maybe you should put your money in a savings account and then send an email to the bank every month asking them when the interest gets added to the account and see how that goes for you. Maybe they will ask that you take your business elsewhere as who could tolerate such an ongoing irritation. No don’t do that, you may cause the email recipient to blow their brains out and I would not want it said that I motivated you to drive someone to self destruct.
