Yes, that is how some people do it. May as well watch them all so those coupons are available to you the next month.
I understand that the current month's vv expire at the end of the following month (June's vv will expire July 31). When July comes, June's vv will no longer be viewable, but if you've already printed/stored them in your rewards, you can still use them, correct? So would it be best to view each video at the beginning of the month to store them and not wait to view as needed?
