When Nora gets a call from her bank (or credit card company) about suspicious charges she asks what was purchased and they list a series of items as Anna puts them into a suitcase. Card companies do not have get itemised lists of goods purchased from stores. They only have the total amount spent.
When Anna is at Bloomberg's putting items on Nora's tab, one of the items she purchases is an Hermes Birkin bag. This is not an item that would be available for purchase at Bloomberg's, the process for obtaining a Birkin bag is long, exclusive, and complicated and must be done through an Hermes boutique.
