Okay...so I am apparently really dumb with this shipping business. I haven't done this before. When I go to print postage on the USPS website it says I have to enter a date that that package will be shipped. That's fine for the one I am sending, but then how do I print return postage for it to be shipped back to me? It only goes out 4 days and I'm pretty sure Barb won't be mailing back before then...does this date not actually matter? Sorry ladies. Confused.
