I didn't even know it was possible until I read this article. My girlfriend (who lives with me) just logs into my Amazon account when she wants to order something so that she get the free two-day shipping.
We have a Roku 3 with the Amazon Instant Video app as well. I've never watched anything through the Amazon app but she does occasionally (again, using my account).
Knowing his will make things a bit easier, I guess, although we had pretty much worked around it just by sharing my account. Had I known, though, I probably would have shared the shipping with my (and perhaps the girlfriend's) parents.
