Handwritten shopping list in a shopping trolley

Black Friday falls on Friday 27 November 2026, with Cyber Monday on 30 November. Sales often start well before that. You’ll see plenty of “eco” deals.

The lowest-impact purchase is usually the one you don’t make. But if there’s something you were going to buy anyway, a real discount on a better-made version is a good outcome. This guide is a framework, not a deals list. We don’t publish deal prices, because they change by the hour and “was” prices are easy to inflate. Use these checks to decide for yourself.

Step 1: Is it on your list already?

Write your list before the sales start. A good test: would you buy this at full price in January? If not, the discount is the reason, not the need.

Good candidates are things you’d replace or buy anyway: – An appliance that’s failing, where a more efficient model would cut running costs. – A purifier or replacement filters before smoke or allergy season. – Gear that’s worn out: boots, a rain jacket, a pack. – Backup power you’ve been meaning to sort out before storm or fire season.

Step 2: Is the deal real?

  • Check price history. Third-party price-history trackers (websites and browser extensions) can show what an item has sold for in the past, so you can see whether today’s “deal” is actually low. Use one you trust, and check its privacy terms before installing an extension.
  • Ignore the “was” price unless you’ve seen the item sell at that price. Compare against what it sold for over the past few months.
  • Compare like for like. Some sale items are special “doorbuster” variants with lower specs. Check the full model number.
  • Count the running costs. A cheap purifier with expensive filters, or a printer with costly ink, can cost more over a few years.
  • Australia: the ACCC treats misleading price claims as a consumer-law issue. Its guidance tells businesses not to make false claims about the price of any products or services, so check the official page for how that applies to “was/now” pricing. (ACCC, two-price comparison advertising) If a deal looks fake, you can report it to the ACCC.

Step 3: Is the green claim real?

Use the questions from our method page, How we judge green claims:

  1. What exactly is claimed? “Made with 50% recycled polyester” can be checked. “Planet-friendly” can’t.
  2. Who says so? The brand, or an independent certifier whose standard you can look up?
  3. What are the conditions? “Compostable” often means industrial composting only. See what “biodegradable” and “carbon neutral” really mean.
  4. Will it last? Durability, spare parts and repair options usually matter more than a recycled-content badge.

What’s usually worth it

These are categories where a genuine discount can line up with lower impact over the product’s life. Always check the specific model.

Energy-efficient replacements for things that are failing

Look for ENERGY STAR certification (US) or a high star rating on the Energy Rating Label (Australia) when you replace an appliance. Both programs publish their efficiency criteria and product lists, so you can check a model before you buy. (ENERGY STAR · Energy Rating) Renting and curious about induction? See induction cooking for renters.

LED bulbs, if you still have older bulbs

The US Department of Energy says LEDs use at least 75% less energy than incandescent bulbs and last 25 times longer. (US DOE, Guide to Energy-Efficient Lighting, PDF) Buy for the light you need (lumens) and color temperature, not the pack size.

An air purifier sized properly, plus spare filters

If smoke season or a stuffy bedroom is on your mind, a sale is a fair time to buy, as long as the smoke CADR matches your room. Our guide explains how: Best air purifiers for small apartments. Buy a spare filter at the same time if it’s discounted.

Backup power you’ll actually use

Portable power stations are often discounted around Black Friday. Work out what you need to run first (watts and watt-hours), so you don’t pay for capacity you won’t use. See EcoFlow vs Jackery: portable power stations compared.

Durable gear with a strong warranty or repair program

For clothing and outdoor gear, the brand’s warranty and repair policy are worth more than a discount. Some brands run used-gear and repair programs; Patagonia’s Worn Wear is one example. A secondhand or repaired item can beat a new one on a sale. (Patagonia Worn Wear, plain link)

Refurbished electronics from the manufacturer

Manufacturer-refurbished electronics usually come with a warranty and keep a working product in use. Check the warranty length and the return policy.

What to skip

  • Vague “eco” bundles. Packs of reusable this-and-that you won’t use. A reusable item only pays off if you use it many times.
  • “Biodegradable” plastics with no conditions stated. Most go to landfill, where they don’t break down as the label implies.
  • Duplicates of things you own. A second set of bamboo utensils is still more stuff.
  • Cheap versions of things you’ll replace in a year. Fast-wearing gear has a bigger footprint over time than one well-made item.
  • Gadgets that promise “clean air” without a CADR, or that rely on ozone or ionizers alone. The EPA advises choosing air cleaners that produce little or no ozone. (US EPA)
  • Anything bought for the discount alone. If it fails the January test, let it go.

How we chose these categories

  • We focused on categories where buying a better version lowers running costs, waste or replacement frequency, and where you can check that with published data (efficiency ratings, CADR, warranty terms).
  • We haven’t listed specific deals or prices. If we add a live deal later, it’ll show the price at time of writing, the date checked and the retailer.
  • We have not tested specific products for this guide.
