A 10% discount is not a 10% reduction in contribution
Take two candles costing 6 each, gift packaging 2 and assembly labor 1. The set costs 15. At a regular price of 30 with 3% + 0.30 fees, contribution is 13.80. A 10% discount makes the price 27 and contribution 10.89.
The price fell by 10%, but contribution fell by 2.91 ÷ 13.80 ≈ 21.09%. Costs did not fall with the selling price. This example is illustrative, not evidence of buyer demand.
Check the margin threshold separately
With the same costs, a 40% contribution target needs at least 26.85 after rounding upward. A 20% discount from 30 makes the price 24: contribution is still positive at 7.98, but margin is only 33.25%. “Still makes money” and “meets my target” answer different questions.
Check your gift-set offer →Count finished stock and gift components
Fifty two-candle sets need 100 candles. Eighty uncommitted finished candles cover 40 sets, leaving 20 candles to make. That calculation does not prove you have 50 boxes, inserts, ribbons or cards. Check those separately and reserve inventory already promised to other orders.
Choose a campaign your production can support
Halloween, Black Friday, Cyber Monday and Christmas are campaign labels, not evidence that your offer will sell. Confirm supplier lead time, stock, your tested candle’s production requirements and dispatch capacity before promising delivery.
Keep a named version of your plan before the promotion starts. Compare actual sales and accepted production quantities afterward. Use source-linked supplier notes for current terms, and the planning-kit preview for the linked workbook and production records.
