Nope. Read their FAQs, they'll ship you a replacement for free, but you have the return shipping to send the board to them.
Also, you have more than 30 days... they'll do a replacement/repair on the board as long as the Epox warranty is still in effect. I've returned refurbs nearly a year later with them with no problem.
