It’s time for another tablet Flash Sale over at CowBoom; that means rotating offerings of various tablets at deeply discounted prices, all day long. Free shipping, too.

I have yet to crack the code of how they rotate products at CowBoom in sales like this, so I can’t tell you how often they change. At the moment I see a pre-owned BlackBerry 16GB 7″ PlayBook for $90, though, so the prices are definitely worth checking out. While that deal may be gone by the time I hit “publish,” there’ll be plenty of others.
