no price?

[jordantsap]

in fact i dont want to sell for free ok? i  have some products that they have multiple prices and i define these prices to the description of the product.but, when no price in product the jsystem says: "ask for price". So, i want the field 'in some products (not all products) with no price, to unshow it from the frond page.
(((if i wanted it for all the products i go to config and i choose not to ask for price right? but i want to make this happen for some products not all of my products. can someone help??
