NEW YORK ( MainStreet) -- The Colorado technically lost its status as a river back in the mid-1960s when states such as California stopped it from reaching the ocean. Today Amazon ( AMZN) might go through a similar demotion for, well ... the exact same reason. California politicians recently decided the giant Web retailer must do exactly what every other store in the state does: collect sales taxes. Starting this week, the land of Arnold Schwarzenegger will take what in some cases is up to a 9.75% markup on the online retail action within its borders. Amazon tried to sound upbeat about what will almost certainly be higher costs passed onto consumers. Scott Stanzel, an Amazon spokesman, was widely quoted saying the company will continue to offer lower prices and "the operation is not worried about losing business." Analysts close to the stock also tried to sound positive. I've seen Colin Sebastian, senior research analyst with Milwaukee-based wealth management firm Robert W. Baird & Co. making the rounds saying that Amazon has operational room to lower costs and can keep what it charges customers near the current, usually lower-than-competitors' levels. Sebastian specifically talked up something called Amazon Lockers -- essentially, a gizmo'd drop-off container that lets FedEx ( FDX) or UPS ( UPS) deliver items en masse, thereby shaving shipping fees and keeping the total cost to customers closer to Amazon's current no-sales-tax levels. "On the financial side, they have the potential to save on shipping costs," Sebastian told CNBC. "The savings could be as much as 10% to 15%." That might sound like Amazon can remain the undisputed low-cost Web retail champion it has always been. But even a casual ride down this retail river shows it will probably be parched by the state taxation sun. Not just in California Amazon's -- and the Web's -- increasing tax woes are most definitely not limited to California. According to Cromwell, Conn.-based credit card fee research firm Cardfellow, there are nine other states with similar so-called Amazon taxes. Biggies include Colorado, Pennsylvania and New York. And these 10 Web tax-collecting states are just the leading edge of states wanting their cut of the online action. Approximately three dozen are in the middle of moving to so-called "streamlined online sales tax" collections that almost certainly will mean Amazon will need to collect more fees rather than less.
