How can I view all items in my large online shopping cart?

[Beckita]

Customer here, 

I have spent several hours shopping at a store through the Shop app. I have 76 items in my cart. Now I need to go through the items and narrow down what I want. As I have multiple pesto sauces, olives, balsamic vinegars, etc.  I can only see part of my cart! If I delete something a new item pops up on the bottom to take its place.

How do I access all my items?
