If you want to save some money on pricey virtual reality headsets, the long Thanksgiving holiday may be your chance.

HTC said Monday that it would cut the price of its Vive virtual reality headset by $100 over the four days following Thanksgiving, while Facebook’s Oculus Rift buyers will receive VR software discounts.

On Black Friday and Cyber Monday, shoppers can buy a Vive for $699, compared with the regular $799 price. It will be available from online stores like the Microsoft, Amazon, Newegg, and the Vive online portal. HTC also said that Fry’s Electronics would also sell the Vive headset online and in 34 of its brick-and-mortar stores.

Additionally throughout the weekend, shoppers who spend $30 or more on non-video game VR content from the Vive online marketplace will get a $10 discount off their purchases from Black Friday to Cyber Monday, the Monday following Thanksgiving that is heavy with deals from online retailers. HTC will also discount some VR apps by 50% starting on Black Friday, including titles like Star Chart (normally retails for $9.99), The Grand Canyon VR Experience (normally retails for $4.99), and World of Diving (normally retails for $19.99).

Meanwhile, Black Friday shoppers can also get a $100 discount on software purchases related to Facebook’s fb Oculus Rift headset through Microsoft’s online store. People can buy the Rift for its normal price of $599 and they will receive a $100 digital coupon that they can use to buy VR apps and games. A Microsoft store spokesperson said that “customers get a $100 Oculus Store Wallet with purchase of an Oculus Rift,” and that “Oculus Store Codes will be emailed within 10 days of purchase.”

It should be noted that both the Vive and the Oculus Rift require powerful computers to operate, and people should expect to pay at least $500 for a machine with the minimum requirements.

As of now, there doesn’t appear to be a Black Friday deal for Sony’s new PlayStation VR headset that requires a PlayStation 4 or PlayStation 4 Pro console to run. Analysts consider the Vive, Oculus Rift, and PlayStation VR to be the most powerful VR headsets available.
