I really have no idea what to call what I'd like to do, but here it is -

My client usually does bids for the products she sells, and is wanting customers to be able to order everything they want, but not collect payment.

She would get a copy of the order, and then contact the customer to give them a bid, based on what they've ordered.

She figures out shipping separately, too.

At first, I thought the 'showcase w/ prices' was a better option, but it requires the customer to send an email for EVERY item they're interested in.

Is there a way that they could fill their shopping carts, and then hit a button that would work the same as the 'showcase w/ prices' does?
