Much of our current understanding of how consumers shop for goods and services is based on cross-sectional analyses of end-of-trip variables (e.g., basket composition, total spending) that has largely assumed purchase behavior is constant over the course of a shopping trip, however research has begun to demonstrate how an initial purchase can influence a subsequent purchase decision. This suggests shopping behavior may not only vary throughout a shopping trip, but rather is specifically influenced by when a purchase decision occurs within a shopping trip. I build on this foundation through two essays that show how and why a consumer’s in-store purchasing behavior is influenced by both the decisions they have made and the decisions they anticipate to make later. The first essay demonstrates that a consumer’s relative spending— the price of an item, relative to the prices of the other items in the same product category—evolves nonlinearly over a single shopping trip, and this pattern is distinct for budget and nonbudget shoppers. The second essay examines whether and how encountering promotions in-store, but temporally in advance of the promoted product influences a consumer’s redemption decision. These findings suggest that shoppers’ decisions evolve of a single shopping trip as a function of the decisions and evaluations the have made earlier in the shopping trip, as well the decisions they still have left to make. In each essay, implications for researchers and practitioners are presented and opportunities for future research are discussed.

This thesis aims to answer the question how our relation to money will look like in a potential cashless society.  In a world where all cash has disappeared and the only existing way of paying is digital, what will the notion of money be? How are we interacting with it? How is it affecting our way of spending and saving? With the digitalization of money comes a lot of potential problems that may not be as clear in the beginning, and are being over shadowed by the much clearer and easier to grasp benefits. People tend to spend much more when using a card instead of paying with cash. Overspending a budget is easy when borrowing money through services such as “Buy now, Pay later” - payments. There is no difference between paying 50 units and 5000 units when doing it through the internet.  What will this do to us in a future society? By using Sweden as a context, this thesis is exploring how the transition to a cashless society will look like and the consequences it may have. Initially having a user centered-focus, trying to solve problem, the project takes a turn and switches to a more speculative point of view, exploring different possibilities of how we can connect and interact with money. The final proposal includes three probes acting as conversation pieces, enabling a discussion regarding the removing of cash.
