As noted by AppleInsider, Apple has cut flash storage upgrade pricing for 512GB and 1TB modules on some older Macs.
Apple has been charging between $200 to $500 for a 512GB SSD upgrade, depending on the Mac model and base configuration, while the 1TB option sold for between $700 and $900. With the updated pricing, shoppers in the market for a MacBook Air, MacBook Pro, Mac mini, iMac or Mac Pro can save up to $200 on custom high capacity configurations. Alas, the 2015 MacBook does not benefit from the price drop.
