If you think our daily deal coverage was getting a bit heavy, we agree. What you'll see on our main site homepages now will be the best of the best in terms of deals, and those who want everything can still visit our full post on Kinja Deals, which goes up earlier.

The humble and inexpensive cast iron skillet is one of most important pieces of cooking gear you can own, and Lodge's highly-rated 10" model is only $15 today. If you don't own one, you should have no hesitation. [Lodge LCS3 Pre-Seasoned 10-inch Cast-Iron Chef's Skillet, $15]

Buying a mattress sight unseen is a little scary, but Amazon is offering fantastic prices on 100% memory foam mattresses from ExceptionalSheets, today only.

These mattresses have great (but limited) reviews, and only cost $400-$545 today, depending on the size. Best of all, they have a 90 day risk free trial, so if it's not for you, they'll send a courier to your house to pick it up. That should help you rest easy. [10-Inch Gel Memory Foam Mattresses by ExceptionalSheets are 33% Off at Amazon Today]

If you need a good streaming box for any of your TVs, the excellent Roku 3 is down to $77 today on Amazon, which is within a few bucks of an all-time low.

Admittedly, Roku has a lot of competition from the likes of Apple, Google, and Amazon, but nobody can touch Roku's lineup of channels and apps, and there's something to be said for a streaming box that doesn't prioritize its own company's walled garden. Oh, and building a headphone jack into the remote was one of the great innovations of the 21st century. [Roku 3 Streaming Media Player, $77]

It's clear that Dyson makes your favorite vacuum cleaners, and the cordless and compact DC35 is only $175 today on eBay, via Target. That's nearly half off MSRP, and a terrific deal for anyone that wants to cut the cord on vacuuming. [Dyson DC35, $175]

The Intocircuit Power Castle is an old Wirecutter pick for best external USB charger, and I can personally vouch for mine. [Intocircuit Power Castle Series 11,200mAh Portable Charger, $19 with code BETTER17]

If you still drive an old car without Bluetooth, or heaven forbid, even an AUX jack, an FM transmitter is probably your best bet to get your phone's audio onto your sound system. Luckily, these two options from iClever have great reviews, and are very affordable today.

The $29 model is Bluetooth to FM, so everything remains gloriously wireless. But if you don't mind plugging and unplugging an AUX cable into your phone every time you drive, the $22 version will work just as well.

If you have an older speaker system without Bluetooth streaming, this tiny dongle will add it for just $9. All you have to do is run the included AUX cable from the speakers to the dongle, and then plug it into any USB charger for power. [Mpow Streambot Slider Bluetooth Audio Music Streaming Receiver Adapter, $9 with code 4WK8549F]

$25-per-terabyte is the stuff of science fiction. We see this drive at $130 from time to time, but this is the first time we've seen it dip any lower. [Seagate Expansion 5 TB USB 3.0 Desktop External Hard Drive, $125 with code DIG5]

If you prefer faster Prime shipping, or just have some gift cards to burn, Amazon has it for $5 more.

If that's a little overkill, here's a gorgeous and fast 2TB model for $80. [ WD My Passport Ultra Metal Edition, $80]

If this USB charger doesn't have enough ports to keep all of your devices powered up, well, you might have a problem. Even if it's overkill for home, I could see this coming in handy in conference rooms, or while traveling. [Sabrent 60 Watt (12 Amp) 10-Port Desktop USB Rapid Chargerl, $23 with code SWTPCS23]

Today only, Amazon's blowing out a ton of popular Logitech gaming gear at terrific prices as part of their latest Gold Box deal. Inside, you'll find headsets, mice, mousepads, a gamepad, and even a programmable gameboard, almost all of which have been extremely popular among our readers in the past.

While everything in here has sold ratings, the star of the show is undoubtedly the venerable G700s gaming mouse. We've written about it in the past, it was one of your five favorites, and it's one of the most popular items we've ever listed.

Remember, this is a Gold Box deal, so these prices are only valid today. I suspect many of the most popular items will sell out early though, so act fast. [Amazon]

Another Groupon sitewide code has created one of the better PS4 bundle deals we've seen so far. [ PS4 500GB Game System with The Last of Us: Remastered and Wired Headset, $360 with code TAXHACK10]

If you just need the headset, that's an option too. [Sony Silver Wired Headset, $31 with code TAXHACK10]

If you have an old hard drive or SSD lying around, this cheap enclosure can turn it into a handy external drive. We've featured a few deals on these recently, but this model includes UASP support, which promises better performance for SSDs. [Inateck 2.5 Inch USB 3.0 Hard Drive Enclosure with UASP for SSDs, $14 with code SMNZCLJB]
