discount percentage (e.g. everything at 20% or sales from 20% to 50% or even sales up to 50%). Communicate the amount of the discount, it makes it all more real. And DON'T lie: if you write "everything at 50%" you must actually have all the products discounted by 50%, otherwise it's better to write "discounts up to 50%" .
product or service on sale: if the discounts are dedicated to only a part of the products, it is better to also state this in the communication. Always specify what the sales refer to, for example: "up to 20% on bags and leather goods, 50% on clothing".
