Display prices in units even if there are sold in groups of 4

I am just trying to setup some pricing on WooCommerce and seeing if anyone can help.

The shop is restricted to members so it is a pain I cant show you.

So the can of spray is sold at $35 each although it is sold in a pack of 4 bringing the price to $140. My client wants the price to show $35 on the product gallery and single product page then shown as $140 on the checkout page.

Is this even possible?

I have tried min/max quantities but this shows the cart as having 4 items when it should only show 1.

The page I need help with: [log in to see the link]
