+**Things to check**
+- Have you forced a refresh in your browser (e.g. ctrl+F5 in Chrome/Firefox)?
+  - yes/no
+- Have you made sure the first time buyer option is correct? If you're unsure, try it both ways

+- Have you time-travelled this week? Travelling backwards resets the prices, and therefore you must not put prices in from both before & after the time-travel
+  - yes/no
