As part of the 20th anniversary of the launch of the Steam service this week, Valve launched a one-week discount of it Popular Linux-based gaming laptop Steam Deck.

From now until September 21st, you can buy a new Steam deck for the following prices:

• Steam Deck 64GB: $359.10 (10 percent off MSRP)
• Steam Deck 256GB: $449.65 (15 percent off MSRP)
• Steam Deck 512GB: $519.20 (20 percent off MSRP)

Plus, the Steam Deck Dock is also a big 20 percent off this week, as it’s down to just $71.20.

If you’re buying a Steam Deck but want to upgrade its onboard storage, Western Digital this week announced new internal mini SSDs that will go inside Valve’s laptop.

The Steam Deck continues to be a very popular product on Valve’s Steam Store. As of this writing, this is the fifth best selling product in the store, behind Baldor gate 3, Starfield, mortal kombat 1, and Counter-Strike: Global Offensive.

Earlier this year, Valve began selling remastered Steam decks at 20 percent off new versions. Valve says these units have been extensively tested, including features such as “a full factory reset, software update, and extensive testing involving over 100 tests at one of Valve’s facilities.” However, as of this writing, there are no remastered Steam CCs on sale in the Steam Store.

The success of the Steam Deck has led to some competition in the past year. ASUS released the Rog Ally Windows 11 gaming laptop earlier this summer for $699.99.

A few weeks ago, Lenovo announced plans for its own Windows 11-based gaming laptop, the Legion Go. It has several features that the Steam Deck doesn’t, including removable game controllers and a larger 8.8-inch display. It should go on sale sometime in October for $699.
