How sale discounts works???
I set the discount as below, but when customer add the amount in cart, the price does not change.

I think it shows when they continue further but I'm not sure. I don't do mass discounts like that.

You may want to submit a ticket if its not visually changing when you are looking in the cart to reflect it. The way that last line reads is that only 1 of them become that price, the rest of them are still the normal price though.

Thanks for posting, and I'm sorry that you're having an issue with your Invision Community.

Can you go ahead and submit a support ticket please?

I'm going to need to get a little more information about your account to help, and this is best done in a private support ticket.

Thank you! 🙌
