Amazon's signature 30-hour sale, Prime Day, starts Monday night and runs through Tuesday.
And Best Buy is taking direct aim at the online giant's special occasion with its own big deals.
- $99 for a Google Home
- $150 off an iPad Pro 9.7-inch
- $200 off an iRobot Roomba, Dyson Vacuum, or iPhone SE
- A 39-inch Insignia TV for $149.99
- $70 off Apple Watch Series 2
- And $100 off certain computers
The Google Home deal is actually in effect now, and continues all week. The iPad deal is also already active, but is only through July 11.
And there will be more discounts. A spokesperson told GoMN the deals will be featured on the BestBuy.com home page starting Tuesday.
In other news concerning both these companies, Amazon on Monday announced a new tech support service that rivals Best Buy's Geek Squad. Read more about the differences here.
Comparing the deals
We don't know absolutely everything that will be on sale Tuesday, but we can make a couple of comparisons based on the previews.
For example an Amazon Echo will be $89 – half off the regular price of $179.99. The closest competition there would be the Google Home, which Best Buy will have for $99 – that's $30 off the normal price. (The smaller Amazon Echo Dot is going to be super cheap at $34.99.)
Or the TVs. Amazon's got a 40-inch 1080p TCL TV for $199.99 – you can compare that to Best Buy's 39-inch Insignia that will be $149.99.
It's hard to compare much beyond that. Amazon doesn't appear to have any discounts for Apple products, while Best Buy has at least a couple deals with the iPad and Apple Watch.
Amazon is promising 50 percent off select video games. Best Buy lists none in its preview, but there very well could be some Tuesday.
Our advice? If you're looking at a deal on one of the sites, take a couple minutes to comparison shop on the other – just in case there's an identical or similar item for a deal you like more.
