Shopping Bag or Cart Capabilities?

I'm build a site to support my delivery service. I want my customers to be able to select the items them want from my site and place in a shopping bag or cart. Since I operate on a cash basis, customers do not pay until I deliver the goods. They would use the bag or cart to simply select the items they want delivered, not pay for the goods. By having this feature, it would be easier for me to assemble the order prior to delivery. Is such a tool available on Homestead?
