Black Friday 2026: The Strategy That Actually Works for Chilean Online Stores

Every year I see the same story. A store owner messages me in October saying "I want to do something big for Black Friday." I ask what they have in mind and they say "put everything at 30% off." That's the recipe for losing money.

Let me tell you two real stories from Black Friday 2025. I changed the names, but the numbers are exact.

The store that discounted 200 SKUs

Store A sold home accessories. They discounted their entire catalog between 20% and 35%. Generic banners, a social media post, and wait.

Result: sales went up 40% in volume, but margins dropped so much that profits were lower than a regular weekend with no promotion. The team collapsed processing 3x their usual volume, and three customers left negative reviews because of delays.

The store that chose 8 hero products

Store B sold personal care products. They selected 8 products with healthy margins and enough inventory. A dedicated landing page, new photos, a pre-negotiated rate with their courier, and pre-written WhatsApp responses.

Result: that weekend accounted for 15% of their monthly revenue, with healthy margins and zero complaints. Two products sold out by 3 PM on Friday, and they communicated it as genuine scarcity.

The difference wasn't budget. It was focus.

Checklist for choosing your hero products

Not every product deserves the spotlight on Black Friday. Use these criteria:

• Minimum 40% margin before the discount. If your margin is 25% and you offer a 20% discount, you're working for free.
• Enough inventory to cover at least 3x your normal weekly sales. If it sells out in 2 hours, you lose all the traffic that arrives after.
• A product people are already searching for. Check your analytics: which product pages get the most visits but have a conversion rate that could improve? That product with a real discount will convert.
• A product that photographs well. You need it to look good in a banner, in an Instagram story, and in a WhatsApp message. If it's a product that's complex to explain, it's not a hero.
• No supplier issues. If your supplier takes 15 days to restock and you run out, you'll have the worst Monday after the best Friday.

Aim for 5 to 12 hero products. Enough variety for the customer to browse, but few enough to keep your message sharp.

SERNAC is watching

This is no joke. SERNAC -- Chile's consumer protection agency, similar to the FTC in the US -- monitors prices before and during Black Friday. If you raised a price in September to lower it in November, they can fine you and, worse, publicly expose you. Chilean consumers are increasingly savvy -- they use tools like Knasta, a local price-tracking website, to check price history.

Simple rule: your Black Friday price needs to be the lowest that product has been in the last 90 days. If you can't offer that, leave it out.

Infrastructure that needs to be ready

The most brilliant strategy falls apart if your site can't handle the load or your payments fail. Technical checklist:

• Payment processor: Flow and Transbank (Chile's two main payment processors) receive brutal traffic spikes on Friday. If you use Flow, confirm your plan supports the volume. If you have both, keep them both active as backup.
• Courier: negotiate rates and capacity before November 15. Not the 25th. Your courier is overloaded too.
• WhatsApp Business: set up quick replies and your catalog. In Chile, WhatsApp drives more Black Friday sales than email. Have someone dedicated to that channel for the weekend.
• Website: deactivate every plugin or app that isn't essential. Every extra millisecond of load time is a sale walking away.
• Packaging supplies: do you have enough boxes, tape, and filler paper for 3x your normal volume?

Black Friday is won in October

If you're reading this during Black Friday week, you're already late for half of this list. The campaign is planned a month in advance, executed in one week, and evaluated in December. Choose your heroes, prepare your infrastructure, and resist the temptation to discount everything. Fewer products, better executed -- that's the formula I've seen work in Chile over and over again.
