You can now find the Kobo Wireless e-reader on walmart.com. You can also find it in brick-and-mortar Wal-Mart stores, so it all works out.
Remember: the Kobo comes in three colors (lilac, onyx, and silver, also known as pink, black, and, uh, silver), and walmart.com has free shipping, too.
Why bother getting into fights at the store when you can have the friendly UPS truck drop it off on your doorstep?
