Discount for single product without create a rule for hidden category

[ermes]

Hi forum,
I would like to know if there is a plugin that allows me to set a discount for a single product without creating a rule and / or hidden category.
I have to set manually the discounts for each individual product and I would like to display it with the stroked price.
Tnx!

although frowned upon if your tax and discount setups are quite simple you could try the Over ride price in the product ...

But so i not view the discount. There isn't a custom field plugin that do it?
