How can I restore hidden prices on my collection pages using Turbo theme?

[MRPTerri]

we hide the prices on our collection pages (not product pages)
eg: https://www.mrpoppinsandco.com/collections/beach-towels

in the past this was done with some CSS. 

.thumbnail .price span.money {

display: none;

}

we'd like to show the prices on our collection pages again now, but since going to Shopify2 and getting a freelancer to do that, the css has gone so i can't revert it.

can anyone help me reenable collection prices again?

we use Turbo theme.
