Working With Items in Marketplace Cart

I have multiple questions… As I went through the marketplace, I added the items I thought I wanted to my cart (There is no wishlist capability). Now I have 37 items in my cart that I can’t click on to be sure I want them and I can’t delete them if I don’t during checkout.

  1. How do I edit the items in my cart? I can’t delete them. Do I have to start over and troll the entire marketplace AGAIN and hope I don’t mess up?
  2. How do I view the items in my cart to be sure I still want them? I found if I click on “Cart” from the marketplace and then click on the image, I can view the item)
  3. Why is there no “Wishlist”? See Amazon, ebay, or almost any other online site.
