Remember when I told you about McDonald's Japanese Mega Mac? Yeah, it was this post. In fact, a reader even brushed it off as no big deal. Well, according to Mainichi, the Mega Mac is a very big deal in Japan:

McDonald's Japan has been forced to limit sales of its new Mega Mac hamburger to counter low stocks resulting from its huge popularity. Customers who have been unable to buy the 350 yen hamburgers due to a shortage of stocks are being handed coupons enabling them to buy them next time for 190 yen. The company had planned to sell the hamburgers until Feb. 4, but it is now planning to extend the sales period for at least one week because of their popularity.
