No deals here — that is the point. This page is the math that checks the deals every other site is shouting at you on 27 November, done with a free percentage calculator that runs in your browser. Every number below is a labelled worked example or a sourced, date-stamped fact; no deal is listed, and the only real price on this page is the site’s own Coloring Book Pack above — €7 at its everyday price, because a gift that costs seven euros once never needed a discount to be worth giving.
What does ”% off” actually cost?
Multiply, never re-add. The sale price is the original price times (1 − percent ÷ 100):
$60 at 30 % off → 60 × (1 − 0.30) = 60 × 0.70 = $42
The calculator’s minus Y % direction does this and shows the line behind the answer, so it can be checked by hand. The reverse question — “the tag says $84, down from $120; what percent off is that?” — is the change from X to Y direction: 84 ÷ 120 = 0.7, so 30 % off. Both directions get used all weekend.
How do two discounts stack?
They multiply, they do not add. “30 % off, plus an extra 20 % off for members” is not 50 % off:
| Step | Arithmetic | Price |
|---|---|---|
| Original | — | $60.00 |
| First discount, 30 % off | 60 × 0.70 | $42.00 |
| Extra 20 % off that | 42 × 0.80 | $33.60 |
| What you paid overall | 0.70 × 0.80 = 0.56 | 44 % off |
| A true 50 % off, for comparison | 60 × 0.50 | $30.00 |
The second discount applies to the already-reduced price, so the combined cut is 44 %, not 50 % — on $60 that difference is $3.60; on a $600 appliance it is $36. The rule generalizes: two stacked discounts of a and b leave you paying (1 − a/100) × (1 − b/100) of the original.
Was the “was” price real?
The arithmetic can tell you what the discount is; it cannot tell you what the price was in October. $84 against a “was $120” is 30 % off — that part is math. Whether $120 was ever charged is a price-history question, and it has a method: the deal-check guide walks it step by step — the price-history lookup, the price per unit, the rules an honest “was” price follows and which product categories actually get the biggest discounts. Independent price-trackers exist for exactly that; use one before believing any “lowest ever” claim, here or anywhere.
Which is better — percent off or a fixed amount off?
It depends on the price of the thing, and the crossover is simple arithmetic:
- $10 off a $25 item is 40 % off — a fixed amount crushes percentages on cheap items.
- 20 % off a $120 item is $24 — percentages win on expensive ones.
- On a $50 item, 20 % off and $10 off are exactly the same (worked example: 50 × 0.20 = 10).
So a “$10 off everything over $25” coupon beats “20 % off” on anything under $50, and loses above it. One multiplication settles it for any item in your basket.
What is “buy one get one half price” really worth?
BOGO50 means paying full price for one and half price for the second — 1.5 × the price for 2 items, so 0.75 × on average, which is 25 % off across the two (worked example: two $40 items cost $60 instead of $80). Sellers like the framing because “half price” sounds bigger than 25 %. It is genuinely good when you needed two of the thing anyway; when you needed one, you bought a second at half price to save less than the second item costs. The same math covers “3 for 2” — pay 2 × for 3 items is 33 % off across the three, and only a deal on things you would have bought three of.
How do I compare sale prices per unit?
The sticker does not compare itself. Divide price by amount:
| Pack | Price | Per 100 g |
|---|---|---|
| 500 g | $4.50 | $0.90 |
| 750 g | $6.30 | $0.84 |
The bigger pack wins here — but a “30 % off” sticker on the small pack flips it back ($4.50 → $3.15 → $0.63 per 100 g). These are worked examples, not shelf prices; the habit is the product. Percentages the percentage calculator does instantly; the per-unit division is one line of arithmetic by hand.
When is Black Friday 2026?
Friday 27 November — the day after Thanksgiving (Thursday 26 November). The weekend shape is seller-side knowledge, not a promise: Etsy’s own seller guidance tells shops to run deals the entire Black Friday weekend, as percentage-off, BOGO or free shipping (read 22 September 2026). Offers starting days early and running past the weekend are normal — which is exactly why the checking math, not the calendar, is the useful skill.
What this page will never do
List deals, quote “best” prices, take affiliate money, or invent a discount. The one product it shows is the site’s own Coloring Book Pack at its everyday €7 — presented as a gift, never dressed up as a deal. The percentage calculator is free, needs no account, and computes six things — percent of a value, share as a percentage, change between two numbers, plus and minus a percent, and VAT in both directions. For the question behind all of this — is the deal actually cheaper? — the deal-check guide is the longer answer. Use the math on everyone’s numbers, including ours.
