Is it allowed to put the discount price in the gig picture?

So far I haven’t seen anyone post for example: crossed out $15, and big text SALE $10 on the first gig picture, like discount.
New Year is coming soon, and customers will be expecting discounts.

It is not forbidden.
You can’t put stars ⭐ But there is nothing in TOS regarding discounts
