Is certain promotion allowed (depending on what board you post it in?)

for example if you know of non scam websites (that arent viruses)

can one for example promote themselves with like coupon codes and stuff?

(IE using an example Go to iheartraves.com and use coupon code "example" at checkout for 10% off) <---delete this part if not allowed pls)

would something like that be allowed on the league boards?

or is it not allowed on league boards at all? (obviously i wouldn't want to post it in gameplay and balance but what about like GD or or misc?)

edit: I know of the rule "Account, Product, & Service Promotion

Moderators will look for the following: Advertising for product sales, trading, reward programs, or gifting of any kind Advertising of transactional services offered by individuals or companies"

but Im more asking if its ok to put in a post where the point of your comment isnt to give out the coupon

but you have it as a secondary thing
