I bought mine online last friday... I did call to verify that it would be here in time and the lady thought it would be no problem. She also said that since I was hunting game that did not need to be tagged I could carry my print out with the confirmation number with me if the license didn't show up in time for some reason.

Also when you do the 5 day special hunting it asks you to specify the begin and end date. That is printed on the confirmation as well I believe.
