Welcome to Worth it, where Filter editors spotlight one genuinely good discount on something we’ve tested and loved. Each week, we filter endless sales so you don’t have to.
What’s the big deal? Anyday, the brand behind our readers’ favorite food storage containers, has temporarily discounted all of its square containers by 15% off with the code SQUARE15, for up to $63 off. The brand doesn’t often have sales, and this one ends on 27 September.
What we love
We’ve already extolled the virtues of Anyday’s plastic-free containers, which double as cookware that you can pop in the microwave, oven, freezer and dishwasher.
But the square dishes in particular may have changed lunch for me forever. I recently made salmon poached in olive oil in five minutes using Anyday’s medium square dish. Then I prepped, cooked, ate from (don’t judge) and stored the leftovers in the same dish, and later I will easily reheat that dish for dinner. The fillets fit neatly thanks to the square shape, which also made it easy to eat out of (no tipping over).

To cook, all I had to do was place frozen fillets in the dish and douse them in olive oil, cover in lemon slices and sprinkle with dill. Then I popped it all in the microwave for a few minutes. Yes, you can microwave fish with this container – I too was skeptical until I tried – thanks to the lid’s vented knob that lets out steam. The fish came out moist, flaky and disturbingly indistinguishable from oven-baked salmon.

A word to the wise: the dish’s glass is very hot to touch fresh out of the microwave, though it cools quickly once out. The same borosilicate glass that makes these containers able to handle extreme temperature swings also makes them heavy, and they will shatter if dropped, so handle them with care. But you don’t need to worry about them slipping out of your hands as you wash them, because they’re dishwasher-safe.
The brand offers round dishes too, but the square ones are more easily stackable and a better shape for baking brownies or casseroles (and making fish fillets). If you’d rather skip the glass entirely, Anyday has silicone food storage containers that we called “the perfect food storage” due to their durable, leak-proof and plastic-free design.

Who should buy it?
Buy it if: You want to prep, cook and store food in the same container and cut down on number of dishes to wash.
Skip it if: You’re a bit of a klutz.
Bottom line: At 15% off, this flash sale is a good excuse to stock up on something we would recommend at full price anyway.
Why you should trust our recommendations
We work for our readers, rather than the brands we write about. Every item we recommend is something a Filter editor or contributor has personally tested and can vouch for. On occasion, we may present a close substitute from the same brand and explain any differences from the original.
We scour competing retailers for the lowest prices on any item, and we use price-tracking tools such as CamelCamelCamel to check price history and ensure the discounts are truly good value, rather than a faux markdown. (So while we love sharing good deals, we also aren’t afraid to call out the unimpressive ones.)
