More Apple Watch sales are here, this time for Series 4 cellular and GPS models over at Staples, as part of a 48-hour online flash sale.

Apple Watch Series 4 aluminum models with cellular and GPS are being price cut to the following prices (includes Nike+ models):

• 44mm Cellular – $429.99 (save $260; 38%)
• 40mm Cellular – $399.99 (save $250; 39%)

Also available are stainless steel Apple Watch Series 4 models with Milanese Loop:

• 44mm Cellular – $549.99 (save $570; 51%)
• 40mm Cellular – $499.99 (save $560; 53%)

Cellular Apple Watch models require a data plan from your wireless carrier and will cost you normally an extra $10 per month to use, if you want to be able to send and receive message, phone calls, listen to music and more without your iPhone. They will work fine without a cellular connection.

Compared to the latest Series 5 model, the Series 4 only lacks the always-on Retina display, which is not exactly a deal-breaker. You still have the ECG app with the Apple Watch Series 4, which is no longer available from Apple’s website.

Apple will most likely debut Apple Watch Series 6 sometime soon, hence these deep discounts.
