I'm looking into a MBP 15" Retina with the specs maxed out to a 2.8GHz i7 and a 1TB SSD. I was looking at Best Buy because they're currently running a sale, but they list the model number as Z0RG1LL/A. See here: http://www.bestbuy.com/site/apple-m...lver/4357900.p?id=1219736050738&skuId=4357900 I can't find this model number on the official Apple support site. See here: https://support.apple.com/en-gb/HT201300 Is this some special retailer SKU? And here's the potentially stupid question... if I buy this MBP from Best Buy, am I getting the same unit as I would if I bought directly through Apple?
