Amazon’s Prime Day is just hours away, and the online retailer wants to keep anticipation high. To that end, the company has unveiled a sneak peek at some of the deals you can expect throughout the 30-hour extravaganza.

As is typical for Amazon, the company’s preview includes some generic promises, such as up to 40 percent off gaming laptops—but a handful are truly excellent deals. We’ve picked the top three that jumped out to us. Keep these on your radar, and when Prime Day sales truly kick off at 6 P.M Pacific / 9 P.M. Eastern on Monday evening, we’ll be tracking the best of the Prime Day tech deals on PCWorld.com.

Note: To take advantage of Prime Day sales, you must be a member of Amazon Prime. This service is Amazon’s $99-a-year club that offers free two-day shipping on orders, as well as a litany of frills like free premium video and music streaming, free online photo storage, a Kindle lending library, and various promotional offers. New Prime members get a free 30-day trial, which means you can sign up, get the Prime deals, and then dump the membership before the $99 fee kicks in.

Amazon Echo for $90

This is easily the best deal yet for Amazon’s smart speaker. The lowest ever price was during its pre-order period, when early adopters could snag it for $99. This undercuts that by $10, and the lowest price on CamelCamelCamel by $40. The Echo—powered by the Alexa digital personal assistant—is a fantastic smart speaker for those looking to get started with smart home gadgets.
