App to apply product discount after product has been on site for X time

[jake_mitchell]

Hi,

Has anyone got a recommendation for an app that can apply discounts to products when they've been on the site for a certain amount of time. 

For example,

• if product was created 30 days ago reduce by x%
• if product was created 60 days ago reduce by y%

Just wondering if anyone has had any good experiences with apps they could recommend.
