Well this one you will want to drop everything and register pronto!
It looks like the Sample Showcase is back and this is a seriously awesome freebie if you get selected.
How it works is that you register for the program and then if you fit the demographic they are looking for, you get a whole bunch of samples in the mail. Last time around I did not qualify but I know tons of you got these boxes and they were filled with great samples from a variety of manufacturers.
If you register now, you should get an email from them when the next batch of boxes are available. Otherwise they will announce it on the web site and you can request it at that time. These are first come first serve and I can tell you from experience the web site was a mess the last time they offered this. It is much better to get an email heads up to request your box than try to get through the web site the day it is available.
Once you register be sure to keep an eye out for a confirmation email. This does not guarantee you will get one of these boxes but it sure puts you ahead of the game.
