Stop showing products under certain price

I am using a xml import for a client of mine. It took forever to finetune the import but the client wishes to stop selling products under a certain price point, since they would take a loss on it.

I am using Woocommerce as the e-commerce platform, and instead of changing the import template, I was wondering if it was possible to stop showing these products through Woocommerce by adding a function to functions.php to achieve this.

Thanks!
