MARKETPRESS ECOMMERCE - can it be used to display and not sell products

Hi there.
One of our clients is a design service that utilized in stock accessories. They want to be able to allow their customers the capability to view products, place them in a cart, but purchase them later offline. Can marketpress do this without utilizing a payment gateway?
Also, can marketpress allow registered users only to access the product catalogue?
Thanks so much!
