What should I stock up on during Black Friday?

Things you use every week and that keep for months: toilet paper, paper towels, laundry detergent, dishwasher pods, trash bags, diapers, dog food and coffee pods. They do not spoil, and a low price per unit on a big pack saves money on every order until spring.

How do I know a Black Friday price is a real deal?

Compare today's price per unit with the lowest price per unit the same listing has had in the last 90 days. That low is the price to beat. If a sale price is at or under it, the deal is real. If it is above it, the sale badge is only a label.

Is the biggest pack always the cheapest per unit?

No. A bigger pack is often cheaper per unit, but not always. Check the price per unit for each size before you buy.

How much to buy

Buy what you will use before the next big sale, not more. Paper goods, trash bags and detergent keep for a long time if they stay dry. Diapers go by size, so buy only the size your baby wears now and maybe one up. Dog food and coffee pods carry a best-by date, so check it on the listing and buy what you will finish before then.

Before you buy

Black Friday prices change during the day, and a deal can sell out or end early. Open the price history for any product to see how today's price compares over time, and confirm the price on Amazon before you order. Amazon shows its own delivery date at checkout, so order early in December if a holiday guest is coming. More checked deals are on the Black Friday page, and the method is in how Dealophant calculates price per unit.

Common questions

What should I stock up on during Black Friday?: Things you use every week and that keep for months: toilet paper, paper towels, laundry detergent, dishwasher pods, trash bags, diapers, dog food and coffee pods. They do not spoil, and a low price per unit on a big pack saves money on every order until spring.
How do I know a Black Friday price is a real deal?: Compare today's price per unit with the lowest price per unit the same listing has had in the last 90 days. That low is the price to beat. If a sale price is at or under it, the deal is real. If it is above it, the sale badge is only a label.
Is the biggest pack always the cheapest per unit?: No. A bigger pack is often cheaper per unit, but not always. Check the price per unit for each size before you buy.
