Leveraging meal kit coupons is the extreme couponing of our times—a capitalism hack-a-thon right up there with trial yoga classes and attempting to cancel your Adobe subscription. Meal kits like HelloFresh have always been a better deal than they get credit for, even at full price: It’s actually hard to recreate meal kit meals for less than you can get the recipes delivered to your home. But it’s especially worth it when you can find a HelloFresh coupon, promo code, or discount at more than half off.

I’ll admit I wasn’t that sold on HelloFresh when I first tried it most of a decade ago. It was useful, it got me out of my staid routines, but I wasn’t impressed with the selection. It felt a little basic. But lately? Honestly, it’s kinda cosmopolitan these days, after expanding to a dozen countries and absorbing the supply networks from multiple other meal plans. When I last tested the HelloFresh meal kit (7/10, WIRED Recommends), I was surprised to find myself cooking credible home renditions of ramen, ponzu-plum beef stir fry, and Southwest-accented pork roasts. And when I’m able to pick up a HelloFresh discount code, it’s generally less than I’d spend on groceries anyway. So it’s a good moment to try out a lifestyle where the food comes in the mail.

HelloFresh Student and Discount: 55% Off, Free Shipping, Plus Extra 15% Off Education Discounts Available via UNiDAYS

HelloFresh meal kits are pretty amenable to dorm life when ordering the ready-to-eat meals—or just saving time during grad school instead of ordering pizza, by letting the Internet do your shopping and meal planning. But student budgets tend to be tight, of course. And so there are steeply discounted HelloFresh coupon codes specifically for students. Follow the link here for a HelloFresh education promo code offering 55% off your first box, free shipping, and a continuing discount of 15% off for the first year.

Discounts also apply to teachers who’ve never tried HelloFresh. Educators and school employees can get up to 12 free meals spread out across 3 boxes, plus free shipping. Click here for the HelloFresh promo code, or go here for more information about educator discounts.

Note that the student and educator discounts don’t combine with any other HelloFresh discounts or promotions.

Give $40, Get $10 With the HelloFresh Referral Program

Already a HelloFresh subscriber? You’re still eligible for discounts if you pass along subscription information to your friends. Here’s how: Send your friends a $40 discount for their own affordable meal kits. Once they sign up using your HelloFresh referral code, you’ll also get a $10 credit on your next delivery.

These discounts stack. So if you sign up multiple friends with your referral code, you get multiple $10 discounts. Check out the HelloFresh meal kit referral program here.

Take Advantage of HelloFresh Come Back Offers

Some of these discounts are only available to new HelloFresh customers. But there’s a hack to getting discounts anyway. After you pause or cancel your subscription, check your inbox after the next few days or weeks. Often, you’ll get HelloFresh coupon codes for discounts.

Typical HelloFresh “come-back” offers after a canceled subscription include: $100 to $180 off (spread out over several meal boxes), free shipping on the first box (after re-subscribing), free items such as dessert, breakfast, or an extra protein per meal, or a free meal box is offered after a break. Typical retention offers, for when customers try to cancel, include: 40% off the next box, if you decide not to cancel, or 25% off the next two meal kits. None of this is failsafe, of course, offers vary for each customer. But as with magazine subscriptions, sometimes canceling, or trying to cancel, will lead to a good discount offer from a company eager to keep your business.

When to Save the Most on HelloFresh Subscriptions

HelloFresh almost always has some sort of deal going, whether to bring in new customers with an especially choice HelloFresh coupon, or bring back previous customers with HelloFresh discount codes and retention offers. But summer tends to be one of the times they offer the steepest discounts, including 10 free meals across several boxes, complimentary appetizers, free ready-made items, or free shipping on select boxes.

The other big times for HelloFresh coupon codes are around Black Friday and the end of the year. HelloFresh often launches limited-edition holiday meal boxes and themed meal kits, not to mention discounts for returning customers looking to cook more at home as part of New Year’s resolutions.

But you already know about this, because F_g is what normies call an object’s “weight,” and for a given volume, weight depends only on the density. Now, if you dropped these blocks in a lake, obviously the styrofoam would float and the steel would sink. So clearly it has something to do with density.

What if you had a block of water with the same volume? If you could somehow hold this cube of water, it would feel pretty heavy, about 62.4 pounds. Now, if you place it carefully in a lake, will it sink or bob on the surface like styrofoam? Neither, right? It’s just going to sit there.

Since it doesn’t move up or down, the total force on the block of water must be zero. That means there has to be a force counteracting gravity by pushing up with equal strength. We call this buoyancy, and for any object, the buoyancy force is equal to the weight of the water it displaces.

So let’s think about this. The steel block displaces the same amount of water, so it has the same upward-pushing buoyancy force as the block of water. But because it’s denser and has more mass, down it goes.

In general, an object will sink if the gravitational force exceeds the buoyancy force, and it will float if the buoyancy force exceeds the gravitational force. Another way of saying that is, an object will sink if it’s denser than water and it will float if it’s less dense.

And right in the middle an object will neither sink nor rise to the surface—we call that neutral buoyancy. Humans are pretty close to neutral because our bodies are 60 percent water. That’s why you feel weightless underwater—the buoyancy force pretty much offsets the gravitational force.

Avast! Hold on there, matey. Aircraft carriers are made of steel and weigh 100,000 tons, so why do they float? Can you guess? It’s because of their shape. Unlike a block of steel, a ship’s hull is hollow and filled with air, so it has a large volume relative to its weight.

But what if you start filling it with cargo? The ship gets heavier, which means it must displace more water to reach that equilibrium point. In general, when you launch a boat or ship into the water, it’ll sink down until the weight of the water it pushes aside equals the boat’s total weight.

When I reviewed the GR III, I wrote about how much I liked snap focus mode, which allows you to set a predetermined focus distance regardless of the aperture. I set up my GR III to use autofocus when I half-pressed the shutter and snap when I quickly pressed, so that snap focus fired off the shot at my predetermined focus distance (usually 1.5 meters).

All that remains, but there is also now a dedicated letter, Sn, on the mode dial that sets the camera in Snap Focus mode, which allows you to dial in not only the distance you want focus at, but also the aperture you want to lock in. You can control the depth of field as well. I rather enjoyed this new mode and found myself shooting with it quite a bit.

Should You Get One?

The GR IV debuted at $1,497, which is significantly more than the GR III’s $999 price at launch. Is it worth the extra money? If you have a GR III and are frustrated by the autofocus, I think you will like the upgrade. It’s significant and, if you have the money, well worth it.

If you have any desire to use your pocket camera for video, this is not the one for you. See our guides to pocket cameras and the best travel cameras for some better, hybrid photo- and video-capable cameras. If you want an APS-C sensor that legitimately fits in your pocket, offers amazing one-handed control, and produces excellent images, the the Ricoh GR IV is for you.

Personally, I am holding out for the GR IVx, which will hopefully, like the GR IIIx, be the same camera with a 40mm-equivalent lens. At the time of writing, Ricoh would not comment on whether there will be a GR IVx.
