I might be a bit oldfashioned, but I just feel much safer having a physical product of Adobe Photoshop (ether CC or CS6) in my hands instead of a downloadable file.
I also really dislike having to pay over time and would rather save up money to pay for the product all at once.
I haven't had much luck in calling the support via phone. To my annoyence they redirected my to the webpage.
CC is also available with the pre paid option, if you want to pre pay for the entire year rather than paying monthly, then that option is available here: http://creative.adobe.com/plans
However if you want to purchase CS6 Box version for your own Individual use, you can contact any of our reseller like Best Buy, Walmart, Amazon[NOT AMAZON MARKET PLACE], to buy the retail box version of CS6.
You can purchase it from this link too: http://www.adobe.com/products/catalog/cs6._sl_id-contentfilter_sl_catalog_sl_software_sl_c reativesuite6.html
I hope it helps.
