Well, every time a request is made to '/order' you override the content
of 'requested_item_record' with an empty list (line 40) and 'total_cost'
with a zero (line 41). You should check first if there is already
something in the session. e.g.

if not 'requested_item_record' in session:
     session['requested_item_record'] = []

I cloned you project and simply commented out those two lines.
It seems to work.

Another tip for your repository: add a .gitignore to the root folder
with sth like:
*.py~
*.pyc
venv/

You probably don't need/want those files tracked with git.
