I am looking to buy a 2015 retina macbook pro 13", 2.7GHz, 256GB PCIe-based flash storage. It is $1499 from the Apple store plus tax and $1,424.99 with No tax from Macmall. The saving with tax is $150.91. From what I understand Macmall is a "certified Apple reseller". Does buying from Macmall seem like a good idea? Anyone have experience with Macmall? Comments appreciated - thanks.
