Black Friday was anything but a shopping bonanza, yet sales volumes still ticked upward.  Now, the focus is shifting towards the data picture on Cyber Monday, another important post-Thanksgiving shopping day.  In anticipation, shares of Amazon dropped 5.22 percent to $40.47 in Monday trading, and eBay (EBAY) slipped 6.85 percent to $12.23 on expectations of softer sales.  Other internet retailers also suffered.

The broader online shopping picture will start to emerge on Tuesday, though hyper-competitive discounting and more conservative purchases could hurt online retailers.  Interestingly, deeper discounts at brick-and-mortar outlets are expected to cramp online activity, traditionally a place for aggressive comparison shopping and deals.  On the broader holiday season, comScore projected flat spending, and other projections are also soft.

Still, preliminary traffic figures suggest a bump, and perhaps a better-than-expected result - especially considering the backdrop of serious consumer uncertainty.  Online music sales are also part of the discussion, and reportedly stronger sales at Apple Stores - including iPods and iPhones - could elevate iTunes Store purchases.
