A source within Apple said it’s determined on a case-by-case basis, depending on availability of stock.
Target is discounting its entire lineup of Apple Watch Series 1 models by US$70—that includes eight models of Apple Watch. With the price drop, 38mm models are $199, and 42mm models are $229. Both prices include free shipping. This is a great deal for customers who want an Apple Watch but not necessarily the latest model. The prime differences between Series 1 and Series 2 watches are that the Series 2 devices have a GPS sensor, water resistance, and a better display. (via MacRumors).
