Thanks Made4Uo, I don’t think this a solution for my problem as I have other ways of hiding the price/getting a quote on an item already (such as using Request a Quote + Hide Price).
I’m looking for a way to allow users to either purchase items if they are all listed with prices, OR to allow them to get a quote if at least one of the products in their cart has their price hidden.
The only other option i can see is to only allow items to be quoted, even if they all have a price, and then convert the quote to an order each time.
