Remove price from post

Hello,

I want to remove the price that is on each post thumbnail and below the title.

https://ivebeangrounded.com

i also want to remove all excessive cart prices. It’s a pick n mix store. So if you buy 6 items. its ￡8.95 for all items. But if you only add 5 items, then it’s 5 x ￡8.95 as the discount is only added if 6 are ordered.

I basically want to keep the prices for each item incase I want to change them, but just make them hidden.

What files do i need to change?
