Let me start by saying that I have nothing to do with Sparkfun, apart from being a satisfied customer!
Also that I have a very jaded view of "special offers".
But!
On January 13th, 2011 starting at 9AM MST (That's Colorado, west of center USA), Sparkfun are conducting a publicity stunt which gives you a chance to ring up credit with them! And you have two months to spend the credit, too.
If you like Arduinos, but haven't come across Sparkfun yet, you should visit the site anyway.

For those reading this who think that forums aren't the place for "ads", I would, in general, agree with you. I hope YOU will agree with ME that...
a) Sparkfun is entirely Arduino relevant
b) Their publicity stunt has GENUNE good $tuff for those who choose to participate, and no unreasonable "strings attached".
