Black Friday deals you skipped: how to count what you kept
Black Friday 2026 falls on November 27. By that morning, your inbox will hold dozens of deals you did not need an hour earlier. Skipping most of them is a good outcome, and almost nobody records it. This guide shows a simple way to count the money you kept.
Count the sale price you kept
A banner says a TV is $200 off, down to $299. If you skip the TV, did you save $200 or $299?
You kept $299. The $200 is a comparison to a price that may or may not have been normal. The money that stayed in your account is what you were ready to pay, which is the sale price. So for a skipped sale item, the planned amount is the sale price and the actual amount is $0.
This also keeps the number honest. Planned spend minus actual spend equals the Diff, and only money you chose not to spend counts. Retailers' "you save" figures are not part of it.
Before the day: write your list
Decisions made in advance are easier than decisions made in front of a countdown timer. Take ten minutes this week.
- Write what you actually want and what it costs today. Include gifts.
- Give each item a limit. If the price drops below the limit, you buy the item. If the price stays above, you wait.
- Decide the exceptions, such as a replacement for something that broke.
- Note the date: Black Friday is November 27 and Cyber Monday is November 30.
Many people also observe November 27 as Buy Nothing Day in the US and Canada, and the same list works for that.
On the day: log deals as you meet them
Each time a deal catches your attention, you have three honest choices.
- Skip the deal. Log the sale price as planned and $0 as actual. The full price is your Diff.
- Buy the item. The item was on your list, you have the money, and you wanted the item. Log the purchase and move on. That is a decision too.
- Not sure yet. Put it aside and decide later.
The third choice helps most on a day built to make you decide quickly. Deals that return in a week at the same price were not that urgent. The 24 hour rule works well here.
A worked example
Say you looked at six things over the weekend.
Example amounts only.
| Item | Sale price | What you did | Diff |
|---|---|---|---|
| Headphones | $129 | Skipped | $129 |
| Winter boots | $90 | Bought a $60 pair instead | $30 |
| Stand mixer | $279 | Not sure yet, then skipped | $279 |
| Gift for a friend | $40 | Bought, on the list | $0 |
| Streaming bundle | $15 a month | Skipped | $15 |
| Gaming console | $349 | Skipped | $349 |
That weekend's Diff is $802 ($129 + $30 + $279 + $15 + $349). The gift is logged too, with no Diff, because buying something you planned is a fine result. The point is that the weekend ends with a number you can name, instead of a vague sense of having resisted.
If a subscription deal is a monthly amount, think about it over a year. $15 a month is $180 over twelve months. Keep the Diff Premium has recurring Diffs for this: log a canceled or downgraded subscription once and it counts every month, for up to a year.
Where the money goes next
A number on a screen is nice. Money pointed at something is better. Choose a goal before the weekend and attach a photo of it. When the Black Friday Diff is added, the goal moves, and the skipped deals have a place to go.
You can also move the amount into a savings account yourself. It is a small ritual that turns a good weekend into money you can see in your bank.
If you buy some of it
Plenty of people end up buying a few things on the day. Nothing in Keep the Diff resets, dims or goes away. Log what you bought and carry on. The money you did keep this year is still kept. What to do when you buy something anyway has more on this.
Doing it in Keep the Diff
Keep the Diff is made for this subtraction. Tap to add a decision, enter the planned amount and the actual amount, and save. The free plan logs without limits, and there is no bank connection. The Not sure yet option, added in version 1.4.0, holds a purchase and asks again when you choose. Skip the purchase and the money counts as a Diff.
In December and January, version 1.4.0 also adds a year in review: the total you kept, how many Diffs you logged, your biggest skip and the goals you reached. A big skip from Black Friday weekend can end up as the biggest skip on that card.
Keep the Diff is on the App Store and Google Play, and there are downloads for Mac, Windows and Linux on the download section of the home page. You can also try it in your browser first. Premium pricing is on the Premium page.
