Apple has just added Best Buy’s online store as another channel for iPad sales. Prior to today, customers were only able to purchase iPads at BestBuy.com as reservations for retail pickup. Now, all six models of iPad are available for purchase with free shipping in the US. The current shipping time from BestBuy.com is 6-10 business days with guaranteed delivery before Christmas for the WiFi-only models. BestBuy.com is now the third online store to sell the iPad with a brief stint at Amazon being the first and Verizon being second. Oh, and BestBuy.com charges $0.99 more than Apple – Dealbreaker?!
