Following yesterday’s price drops on certain build-to-order (BTO) Mac mini components, Apple said it will refund the difference to affected purchasers, according to MacMinute readers. “I spoke with Apple Customer Service this afternoon and they will honor price protection for those that purchased the mini within the last 14 days. You must call,” a MacMinute reader writes. As reported yesterday, Apple quietly cut prices on the BTO components for its new Mac mini, offering the Bluetooth and AirPort Extreme wireless option for US$99 (was $129), the 1GB DDR333 SDRAM upgrade for $325 (was $475), and the 80GB ultra ATA hard drive upgrade for $50 (was $80).
