Like a boot to CompUSA’s hemorrhaging gut, Best Buy just announced a 52-percent jump in third quarter profits. The nation’s consumer electronics giant received a favorable bump in sales due to a calendar fluke which plopped an extra week of post-Thanksgiving shopping in Q3. Gains that will likely be given back in the shorter Q4 holiday season. Still, with international sales (Canada and China) up 32%, Best Buy is looking solid to close the year ahead of analyst expectations. That should translate to more Geek Squad jobs for whatever that’s worth.
