Everybody's an expert when it comes to packing before a vacation. It's great that you squeezed all that stuff into a carry-on. Now, what happens when you find that must-have pair of shoes or holiday gift? Your options are paying to ship the items or getting an extra bag, and neither of those is ideal.

Turns out there's a travel bag that solves that problem so easily, it's kind of embarrassing that no one's done it before. At least, not as well as the Rollux 2-in-1 Expandable Suitcase:

The simple folding design means you can convert this carry-on bag into a full-size suitcase, more than doubling its carrying capacity in seconds. It's intuitive enough for even the busiest traveler to collapse or expand without instructions, and that extra space can be a godsend for long trips. When you get to your destination, just fold it up and save yourself extra space in the hotel closet. While in its carry-on mode, it can even be worn as a backpack if you're hoofing it for awhile.

This isn't a one-trick pony, either. There's plenty of thought put into the polypropylene material, which has durability and flexibility to spare. Need to pack a few extra shirts in? Feel free to stretch it out. And it's water-resistant, too - a big plus for long hikes in unfamiliar territory.

The modular design doesn't stop with the interior. The wheels are sturdy but can be easily removed if you need that extra inch or two of space in the overhead compartment. Read the rest

Who can forget the moment our president, the man in charge of a nuclear arsenal, coined the word "covfefe"? Sadly, it's easy to forget given the frequency and amount of head-slapping sayings he's given us - not to mention the disposable nature of his favorite mode of communication.

But not anymore. There's now a way to enshrine Donald Trump's words as the age-defining proclamations they truly are, thanks to these framed tweets by Kanye West's favorite president.

Yes, that's one of 45's defining gaffes on a cardstock print, lovingly displayed with beveled matting behind an elegant 10" x 12" gold frame made of New Zealand wood. It's suitable for mounting anywhere you'd like to meditate on the universal truth and eternal mystery of "covfefe," be it the study, living room, bedroom or bathroom. We'd go with the bathroom, but you do you.

It's hard to pick just one of Trump's tweets to transform into wall art, and luckily you don't have to. You can get the same presentation for his classic "sorry losers and haters" burn from May 2013, or the October 2012 insight in which he quipped "I have never seen a thin person drinking Diet Coke."

There's also a ton of non-presidential celebrities who get the gallery treatment. Immortalize the grammatically suspect Twitter wisdom of Cardi B, Soulja Boy, Jaden Smith, Kim Kardashian and other great philosophers of our time in the same golden frame. There are tons of options available, and right now they're all 10% off the MSRP. Read the rest

A few hours of music, an easy way to take calls over the commute. We don't ask for a lot out of our headphones - but looking at the specs on the Aunu Audio M50 True Wireless Headphones, maybe we should. Not only will these things outlast a cross-country trip, but they'll also make it easier for you to communicate no matter what country that happens to be.

The M50s have all the basics you'd need from a tough pair of workout headphones: IPX7 water resistance, Bluetooth 5.0 connectivity, a tight ergonomic fit. But the battery life is the first thing that really raises eyebrows about this one. A single charge gets you 6 hours of playtime, but you can extend that to a jaw-dropping 150 hours with the wireless charging case. That means if you listen to music less than 6 hours each day, you could potentially go an entire month without plugging it in.

That alone would make this a perfect vacation audio set, but the M50 also comes with an app capable of translating more than 30 languages on the fly. That's pretty invaluable no matter where you choose to take it.

Pick up the Aunu Audio M50 True Wireless Headphones + Companion Translator App for more than 55% off the list price today. Read the rest
