✕Common Mistakes
C'est de -20% cette semaine.
The preposition "de" is not used after "c'est" when stating a discount.

The demonstrative must agree in gender; "semaine" is feminine, so use "cette".
-20% cette semaine c'est.
Word order sounds unnatural; keep the introductory "C'est" at the start.

Cultural Tip
In French ads the percentage is usually written with a minus sign (‑) and spoken with "moins" (e.g., "moins vingt pour cent"). The phrase is informal but perfectly acceptable on signs; in a formal written announcement you might prefer "Il y a 20 % de réduction cette semaine". Remember that "cette semaine" always refers to the week that is currently running, not a future week.
