The unofficial start to summer is one week away, but anyone looking to shop Memorial Day deals doesn't have to wait until May 25.

Deals are already live at Amazon, where you can save as much as 40%. There are also plenty of savings from the mega-retailer and across the online shopping sphere on the usual suspects, like mattresses, TVs, furniture, and outdoor patio deals. However, plenty of other brands are getting in on early MDW sales — you can grab the Dyson Airwrap i.d. for $150 off and the Bose QuietComfort headphones for $120 off.

We'll be updating all the best Memorial Day deals throughout the week, so if you don't see anything that catches your eye just yet, be sure to check back soon.

Why we like it

What says start of the summer better than slushies on-demand? When Mashable's Leah Stodart reviewed the Ninja Slushi, pointed out the merits of the Slushi over a regular blender: no ice is required, and it keeps drinks frozen while in its cooling cylinder. From cola slushies to frosé, this might just be the ultimate summer drink machine. It has some downsides (sugar-free beverages are a no-go), but if you're a frozen drink enthusiast, this deal is worth a closer look.

Best Memorial Day TV deals

Why we like it

This Fire TV $75 cheaper at Best Buy than the sale price you can find it at on Amazon, but that's only a piece of the picture demonstrating just how good this deal is. Our resident TV expert Leah Stodart pointed out this $264.99 price point is so good that it's less than the sale price of the 43-inch version of Amazon's most basic ember 4K Fire TV. In other words, if you're looking to score a solid deal on a smart TV this Memorial Day, so far, Amazon may not actually be your best bet.
