anyone read this yet?

I pre ordered a CE from best buy..after a week of back and forth phone calls...they cancelled my order abruptly. I immediately went to origin.com and Pre ordered the DDE. NOW, EA has refunded my money. When i return to the EA site to repurchase it says that preorders are not available in my region. I am a US East coast player. Anyone else get this?
