The price to upgrade RAM from 8GB to 16GB is $200 on other Macs, including the iMac and MacBook Air, and this change is meant to keep the fee consistent. Update 6/1: Apple has reportedly informed The Verge that this price change is actually a price correction: Until today, Apple had charged $100 to upgrade from 8GB of RAM to 16GB of RAM, but now that upgrade costs $200 in the United States.
Apple has quietly adjusted the pricing for RAM upgrades in the entry-level $1299 MacBook Pro.
