[quote name='slowdive21']boagman's code isn't working for me today. I did use it yesterday though, so it might not be reusable?[/QUOTE]
Haven't used boagman's myself, but it appears that I'm able to repeat with the one I got from a Family Dollar store (just tried for a second time today).
EDIT: I used the code I got from the local Family Dollar store early Monday morning, then used it again just now (on Tuesday). Trying it for a second time today of course produced no results (or extra points), but I imagine it will be usable again in the days to come, like others have experienced.
