Collection Discount

[JohanLindell]

Hi,

I have created special categories as we will have a big blowout in 2 weeks. I want these categories to have a XX% discount. BUT, the solutions offered by Shopify aren´t good enough. The automatic discount only kicks in at the checkout and the code requires a code. 

I want the RRP to show with the discounted price next to it on category/collection level without manually going trough all products. 

Is there an app for this?
